112. 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.
(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.
(E) As a baby emerges from the darkness of the womb, its rudimentary sense of vision, which would deemed legally blind for an adult, would be rated about 20/500.

OA-D. Would be great if you could please explain rationale for all the options

"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.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
