Hi student
Theta waves have a frequency of 4-7 cycles per second and occur mainly in the parietal and temporal regions of the cerebrum. They are normal in children, but do not usually occur in adults. However, some adults produce theta waves in early states of sleep or at times of emotional stress.

The correct answer is (4) Theta waves.

Theta waves have frequency between 4 - 8 Hz. They are seen in parietal and temporal region in children. They are seen in emotional stress in adults particularly during disappointment and frustration, and also occur in many brain disorders. The incidence of transient theta component is about 30% in an alert adult. Amplitude of theta component is greatest at 6 - 9 month (up to 150 pV when eyes are closed) of age. The theta component of EEG often accentuates during crying of children. Theta components persist into adult life in 10 - 15% of normal subject.
