Hi j_shreyans,

The correct answer to this Sentence Correction problem is D. The question is testing parallelism. If we simplify the sentence, we get the following:

Kleine-Levin syndrome is characterized by X (cyclical episodes of extreme lethargy, heightened irritability), AND Y (one of the answers).

Essentially the format of the sentence is "The syndrome is characterized by X AND Y." We need to find Y in the answers, and it must be in correct parallel format.

A)appearing confused - INCORRECT

B)they appear confused - INCORRECT

C)may be confused - INCORRECT

D)apparent confusion - CORRECT, yay!

E)had been confused - INCORRECT
