Verb-Tense Series

(A): Incorrect. "That are easily cracked" is unnecessarily wordy; "easily cracked" would suffice. Further, "gradually" is misplaced; it should modify "have been becoming" (a too-wordy phrasing itself) rather than "obsolete," as indicated by its placement.
(B): Correct
(C): Incorrect. "That were easily cracked" is unnecessarily wordy and changes the meaning by suggesting a present in which those security measures are not easily cracked. Further, "being" does not accurately convey the change that the sentence indicates with "become."
(D): Incorrect. In addition to the wordy "that are easily cracked," (D) incorrectly uses "like" in place of "such as." "Like" cannot be used to mean "for example." "Have been becoming in a gradual way" is far too wordy and also is worded improperly to accurately modify the verb "become.'
(E): Incorrect. "Having been so easily cracked" does not correctly function as a descriptor of "security measures." As above, the placement of "gradually" is incorrect to modify "are becoming."

Dear Friends,

Here is a detailed explanation to this question-

With all the recent research into biometrics, security measures that are easily cracked such as passwords and PINs have been becoming gradually obsolete.

A. security measures that are easily cracked such as passwords and PINs have been becoming gradually

B. easily cracked security measures such as passwords and PINs are gradually becoming

C. security measures that were easily cracked such as passwords and PINs are being gradually

D. security measures that are easily cracked like passwords and PINs have been becoming in a gradual way

E. security measures having been so easily cracked as passwords and PINs are becoming gradually

Choice A: This answer choice incorrectly utilizes the present perfect continuous verb "have been becoming"; this tense is only to be used when referring to an action that began at a fixed point in the past and is continuing into the present. Additionally, this answer choice incorrectly uses "gradually" to modify the adjective "obsolete" rather than the verb "have been becoming". Thus, this answer choice is incorrect.

Choice B: This answer choice correctly conveys the meaning of the sentence, maintains proper tense use, and is quite concise. Thus, this answer choice is correct.

Choice C: This answer choice shifts the status of measures such as passwords and pins to the past tense, through the use of the verb "were", implying that such measures are no longer easily crackable. Furthermore, the use of the verb "being" alters the meaning of the sentence completely. Thus, this answer choice is incorrect.

Choice D: This answer choice incorrectly uses the word "like" to refer to an example. This answer choice also repeats the tense-related error seen in Option A. Finally, this answer choice is needlessly wordy due to the use of the phrase "becoming in a gradual way". Thus, this answer choice is incorrect.

Choice E: This answer choice incorrectly modifies "security measures" with the phrase "having been so easily cracked". This answer choice also repeats the modification error seen in Option A. Thus, this answer choice is incorrect.

Hence, B is the best answer choice.
