IMO A

You can eliminate B, and E as those answers make illogical comparison, namely, comparing ' a condition related to appearance than health'

C introduces a parallelism error - 'it is a condition' which is not parallel with 'obesity is a biological disorder'
D introduces a conditional statement - 'if it is a biological disorder'

Approach:

try to speak words in this way

Confusion Over ---> may be

Confusion About ---> may be

Confusion with ---> clearly sounds awkward (drop B)

Confusion concerning ---> clearly sounds awkward (drop E)

Now in GMAT, u almost always prefer WHETHER over IF (if u are not sure when whether should be used and when if should be used) --> Drop D

Whether X or Y is the correct idiom, just like either X or Y

so drop Op C and hence Op A is the answer.

Hope this help!!!!

"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."
