(A) As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it would be rated about 20/500, or legally blind if it were an adult with such vision.
(B) A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500, or legally blind as an adult.
(C) As a baby emerges from the darkness of the womb, its rudimentary sense of vision would be rated about 20/500; qualifying it to be legally blind if an adult.
(D) A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500; an adult with such vision would be deemed legally blind.

"it" apparently can refer to baby ( as well as to a sense of vision) according to our friends at the GMAC.

A would be better revised as "As a baby emerges ..., it's sense of vision..." to indicate that the sense of vision is rated at 20/500, not the baby itself.

B seems to say that the sense of vision would be legally blind as an adult, not the baby.

C semicolon is like a full stop - it divides a sentence into two separate "sentences", each of which needs to be fully independent, i.e. have a subject and verb. "qualifying it to be legally blind" is not an independent, standalone clause.

D Correct with two independent clauses, each with its own subject and verb.

E same problem as B: the sense of vision is not legally blind.

I strongly recommend to search in the forum before posting a new topic. This question was already discussed 3-4 times.

Geva , apart from what you said about A ,Doesnt the sentence also seem to convey a nonsensical meaning that the rating of the vision happened simultaneously with the birth

In a sense, yes.
