Meteor showers and individual streaks of light that flash across the sky every night are generated when tiny flecks of celestial detritus, often no larger than grains of sand or of pebbles, burn up speeding through the atmosphere.
A. grains of sand or of pebbles, burn up speeding - Use of OF is incorrect. More over modifier SPEEDING creates confusion. Incorrect.
B. grains of sand or pebbles, burn up while speeding - Correct
C. grains of sand or pebbles, which burn up while speeding
- Placement of WHICH changes the meaning of the sentence because in this case WHICH refers to "a grain of sand or pebble" and means that sand or pebble burns rather than FLECKS burning. Thus Incorrect
D. a grain of sand or pebble, which burns up as it speeds
- Placement of WHICH changes the meaning of the sentence because in this case WHICH refers to "a grain of sand or pebble" and means that sand or pebble burns rather than FLECKS burning. Thus Incorrect
E. a grain of sand or a pebble, burns up when it speeds
- Its the tiny flecks that burns because FLECKS is plural, use of Singular pronoun & verb is incorrect. Thus Incorrect

I believe the answer is B and not A.
In A, 'grains of sand or of pebbles' means grains of sand or grains of pebbles. But 'Grains of pebbles' doesn't make sense.

A. grains of sand or of pebbles, burn up speeding [hold it]
B. grains of sand or pebbles, burn up while speeding [while parallels when to indicate time factor - Hold it]
C. grains of sand or pebbles, which burn up while speeding [which incorrectly modifies sentence - eliminate it]
D. a grain of sand or pebble, which burns up as it speeds [pronoun it has referent issue – eliminate it]
E. a grain of sand or a pebble, burns up when it speeds [pronoun it has referent issue – eliminate it]

B is better than A

Because which refers to near word, so when we use which in "X or Y " construction, it is ambigues to ey to X or Y it reffers

Clearly between A and B. What is your choice and why?

Why is the usage of which wrong in C...B and C according to me are exactly the same... which refers to 'grain' since 'of sand or pebbles' is a prepositional phrase....

The answer should be 'B' because it is comparison by size which is taking place.

See 'grains of sand or of pebbles' is not correct because we can't say grains of pebbles (pebbles are small stones).
actual parallelism here is 'often larger than X Or Y'
which would then be 'grains of sand or pebbles'.
Hence B.

Somebody needs to correct the OA.

In A "tiny flecks of celestial detritus" are compared w/ "grains of sand" and "grains of pebbles"

In B "tiny flecks of celestial detritus" are compared w/ "grains of sand" and "pebbles"

In B "burn up while speeding" makes sense. So B.

i will pick B

we need to find what should follow "when tiny flecks of celestial detritus,xxxx," burn/ which burn(s)/ burns.
Obiviously 'which burn(s)' is already out coz it modifying 'pebble(s)' not the 'flecks'. so option C & D are out.
'burns' is singular 'flecks' plural so E is also out.
Between A and B - In A 'larger than grains of sand or OF pebbles' -- there is nothing grains of pebbles. It should be either larger than grains of sand OR larger than pebbles.
Only B left

Subject :- "tiny flecks of celestial detritus"(Plural) Verb :- "burn"(Plural)
Eliminate D and E.

A is wrong because ‘of pebbles’ – prepositional phrase and cannot be compared with noun ‘grains’ (parallelism either side of conjunction).However, ‘burn up speeding' – is not correct may be due to wrong idiomatic usage’ .
Eliminate A.

Between B and C, the difference is only 'Which',
which can be ambiguously refer to 'pebble', 'detritus' or flecks.

so better go without 'which'. Hence B.

(A) grains of sand or of pebbles, burn up speeding
(B) grains of sand or pebbles, burn up while speeding
(C) grains of sand or pebbles, which burn up while speeding
(D) a grain of sand or pebble, which burns up as it speeds
(E) a grain of sand or a pebble, burns up when it speeds

"Which" in C and D are modifying pebbles/pebble, which is illogical. Eliminate

A isn't parallel, and "burn up speeding" is plain awful

In E, wrong use of "when"

i am non native. even if we do not know sand is non count and the idiom grains of sand, we can see that "pebbles" contains s and, so, is plural. "grains of +plural" is not possible. this is error in choice a

second error in choice a is "burn speeding through". if speeding can modify burn, we need a comma
burn, speeding through

is correct.

so, even i am non native, there are 2 errors for me to eliminate choice a.
