My only guess is that the verbage "use for" is ambiguous--use for what?--and so D is more appropriate although more verbose.

I say "B". The part "the name that medical practitioners use for jet lag" modifies "Circadian dysrhythmia" correctly.

But OA is D not B....
I chosed B also but... I don't know the difference among B, D and E.



I guess B is the only choice where the modifier for Circadian dysrhythmia has been correctly used.

Answer is D because 'thousands of body's' is different from 'body's thousands of'

A -> should place medical name between commas. Also, 'thousand of the body's' is not a correct idiom
B -> same problem as A
C -> name needs to be seperate from sentence using commas
E -> turns it into a cause and effect sentence (meaning of sentence changed)

D is the best. Circadian dysrhythmia alone, clearly defining it as the medical name for Jet lag, also, 'all of the body's thousands of' is the correct idiom.
