Um, is it A??

correct explain please

Bob Wilber became Sidney Bechet’s student and protégé when he was nineteen and, for a few years in the 1940’s, came as close to being a carbon copy of the jazz virtuoso in performance as anyone has ever come.
(A) as anyone has ever come
(B) as anyone ever had been
(C) as anyone ever had done
(D) that anyone ever did
(E) that anyone ever came

"Came as close to being.... as anyone" is correct idiomatic usage. Options D & E don't have that structure, hence eliminate.

Now, in option B & E - Had is used, implying that it was only in the 1940's that he had come close to being as good as him, which is not what the author is trying to convey, also, " Ever had been" is very awkward, making both those choices incorrect; "Had ever been" is idiomatically better than "Ever had been".

"A" correctly uses HAS, implying that nobody has yet come close to being as good as him; "Has ever come" is correct idiomatic usage.

I hope i made sense.
