A scientist has determined that a recently discovered ancient Chinese weapon, buried since approximately 1300 B.C., is encrusted with silk, a fabric previously thought to have been invented 1,000 years later.

A. A scientist has determined that a recently discovered ancient Chinese weapon, buried since approximately 1300 B.C., is encrusted with silk, a fabric previously thought to have been invented 1,000 years later
B. Buried since approximately 1300 B.C., an ancient Chinese weapon had been recently determined by a scientist to be encrusted with silk, a fabric previously thought to be invented 1,000 years later
C. A scientist has determined that a recently discovered ancient Chinese weapon is encrusted with silk, a fabric previously thought to have been invented 1,000 years later, after having been buried since approximately 1300 B.C.
D. After being buried since approximately 1300 B.C., a scientist has determined that a recently discovered ancient Chinese weapon is encrusted with silk, a fabric previously thought to have been invented 1,000 years later
E. A recently discovered ancient Chinese weapon, buried since approximately 1300 B.C., has been determined to be covered with silk by a scientist, a fabric previously thought to have been invented 1,000 years later

Hi, although I think (A) and (C) are the only choices which sounds right to start with,
I want to know whether we can rule out (B), (D), (E) straight away from the choices, please.

You can rule out B and E straight away because both B and E introduces the passive voice.
The original sentence suggests an active voice that conveys clearly the intended meaning, so no need to switch to the passive voice if and if only all the other choices that contain an active voice are wrong.

In D you can stop reading after : "After being buried since approximately 1300 B.C., a scientist" --- >Modifier problem

C changes the meaning

A is the winner

A scientist has determined that a recently discovered ancient Chinese weapon, buried since approximately 1300 B.C., is encrusted with silk, a fabric previously thought to have been invented 1,000 years later.

A. A scientist has determined that a recently discovered ancient Chinese weapon, buried since approximately 1300 B.C., is encrusted with silk, a fabric previously thought to have been invented 1,000 years later --- sounds correct
B. Buried since approximately 1300 B.C., an ancient Chinese weapon had been recently determined by a scientist to be encrusted with silk, a fabric previously thought to be invented 1,000 years later --- had been - past | recently - present
C. A scientist has determined that a recently discovered ancient Chinese weapon is encrusted with silk, [a fabric previously thought to have been invented 1,000 years later] $$modifier1$$, after having been buried since approximately 1300 B.C $$modifier2$$ -- This sentence means silk was buried and not the weapon
D. After being buried since approximately 1300 B.C., a scientist has determined that a recently discovered ancient Chinese weapon is encrusted with silk, a fabric previously thought to have been invented 1,000 years later -- As explained by Rock750 this sentence says that the scientist had been buried
E. A recently discovered ancient Chinese weapon, buried since approximately 1300 B.C., has been determined to be covered with silk by a scientist, a fabric previously thought to have been invented 1,000 years later --- The scientist didn't cover it with silk, he is the one who found the weapon

Hi, although I think (A) and (C) are the only choices which sounds right to start with,

All the choices, except A, either have modifier errors or change the meaning of the original sentence.

A. A scientist has determined that a recently discovered ancient Chinese weapon, (describes the weapon) buried since approximately 1300 B.C., is encrusted with silk, (describes silk) a fabric previously thought to have been invented 1,000 years later

B. Buried since approximately 1300 B.C., an ancient Chinese weapon had been recently determined by a scientist to be encrusted with silk, a fabric previously thought to be invented 1,000 years later - This option omits the fact that the weapon is recently discovered, which changes the meaning of the original sentence. Also uses wrong form of Past Perfect Continuous (had + been + verb-ing)
C. A scientist has determined that a recently discovered ancient Chinese weapon is encrusted with silk, a fabric previously thought to have been invented 1,000 years later, (what was buried? silk or weapon) after having been buried since approximately 1300 B.C. - Modifier error
D. After being buried since approximately 1300 B.C. (modifies scientist), a scientist has determined that a recently discovered ancient Chinese weapon is encrusted with silk, a fabric previously thought to have been invented 1,000 years later - This sentence means the scientist was buried since 1300 B.C.
E. A recently discovered ancient Chinese weapon, buried since approximately 1300 B.C., has been determined (who determined) to be covered with silk by a scientist (so a scientist covered the weapon with silk), (modifies scientist) a fabric previously thought to have been invented 1,000 years later - All sorts of modifier errors

The sentence has no salient errors as it stands. It makes sense, the subject and verb ("weapon" and "is") are in agreement, and the verb tenses are fine. There is no obvious difference among the remaining choices, so let's go through each. (B) features a few verb tense problems; it uses "had been determined" for no good reason, and it uses "to be invented" to describe an occurrence that took place in the past. (C) misplaces a modifier; "after having been buried" should modify the weapon, but the structure of this choice uses it to modify the fabric. Likewise, (D) uses the same modifier to describe the scientist. (E) is incorrect because the scientist did not cover the weapon with silk, and the scientist is not a fabric. This choice contains serious modification errors.

Choice (A) is correct.
