The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Noradrenaline is one of the neurotransmitters that plays a role in mood changes. If the level of noradrenaline is low for some reason, then the signal-sending activity becomes low, and the person suffers from depression. In such situations, antidepressant drugs are required.
Equanil is used in controlling depression and hypertension.
Here the reason for depression when noradrenaline is low is that the signal sending activity becomes low.
