Official Explanation:
(B) The original passage, as given in choice (A), uses "like" instead of the preferred "such as". Also, with the phrase "both having turned 65 this year" at the end of the sentence, it incorrectly modifies "Neil Diamond and Dustin Hoffman".
Choice (C) moves the modifier after the subjects of the sentence, but with "having turned" now as "turned," a
conjunction is needed between the two independent clauses.
With choice (D), "becoming" is idiomatically incorrect for this sentence, and it incorrectly strings two participial phrases together without a conjunction.
As with the original sentence, choice (E) uses "like" instead of the preferred "such as". Also, this choice is wordy, and the verb tenses don't agree throughout the sentence.
The correct answer is choice (B). It corrects the grammatical problems in the original sentence and is the best answer.
