C) episodes of mouth twitching, drooling and speech arrest on awakening at night

D) developmental delay

This answer is correct.


This EEG shows hypsarrhythmia, a pattern of continuous, high-amplitude polymorphic, generalized slowing with no organized background, and multifocal spikes. Hypsarrhythmia is part of the triad of West syndrome. The other characteristic features of West syndrome are infantile spasms and developmental delay.  (See References)
