- B.Both Statement I and Statement II are incorrect
- C.Both Statement I and Statement II are correct
- D.Statement I is incorrect but Statement II is correct
Show answer and solution
Correct option: A
Solution
Noradrenaline (norepinephrine) is indeed a neurotransmitter released at adrenergic synapses and plays a key role in the "fight or flight" response. Low levels of noradrenaline are clinically associated with depression in humans — this is the basis for using certain antidepressants (like SNRIs) that increase noradrenaline levels. Therefore Statement I is correct, but Statement II is incorrect because low noradrenaline IS a recognized cause of depression.
