Could anyone explain what the answer choice would be for this question.

A. a critique of all chemistry since Robert Boyle as well as a vision of a
B. a critique of all chemistry following Robert Boyle and also his envisioning of a
C. a critique of all chemistry after Robert Boyle and envisioning as well
D. critiquing all chemistry from Robert Boyle forward and also a vision of
E. critiquing all the chemistry done since Robert Boyle as well as his own envisioning of

Thanks.

A 3-2 split, let's look at D and E:

"a critique of all chemistry" in the original sentence is supposed to be a description of what is contained in the essay, however, when we use "critiquing", we are changing the meaning by implying that the act of writing the essay and the critique of chemistry were two seperate actions, which is incorrect.
So, eliminate d, e

"B. a critique of all chemistry following Robert Boyle and also his .." - "his" here is ambiguous, we don't know whether it refers to Boyle or to Humphry Davy
"C. a critique of all chemistry after Robert Boyle and envisioning as well" - Clearly unidiomatic "critique" and "envisioning" don't get along for describing the same essay.

Hence answer is A
