The characteritic features of Lennox-Gastaut syndrome are developmental delay, generalized epilepsy with multiple seizure types, and an EEG pattern of generalized slow spike and wave complexes.  (See References)

C) West Syndrome

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)

D) Nomal EEG

This answer is incorrect.


This is not a normal EEG. This pattern of continuous, high-amplitude polymorphic, generalized slowing with no organized background, and multifocal spikes is called hypsarrhythmia.  (See References)

E) Alpha coma

This answer is incorrect.


This is not alpha coma. This pattern of continuous, high-amplitude polymorphic, generalized slowing with no organized background, and multifocal spikes is called hypsarrhythmia.  (See References)
