Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Anxiety disorders
Option (1) Paralysis — Incorrect. Paralysis is a loss of movement from damage to nerves or muscles, a physical condition, not a disorder linked to a neurotransmitter’s activity.
Option (2) Depression — Incorrect. Depression is linked to low activity of serotonin, not of GABA.
Option (3) Anxiety disorders — Correct. Abnormal activity of certain neurotransmitters leads to specific disorders. Anxiety disorders have been linked to low activity of GABA, the neurotransmitter that normally calms nerve activity. (Schizophrenia is linked to excess dopamine.)
Option (4) Physical impairment — Incorrect. This is a general term for a bodily limitation, not a psychological disorder tied to GABA.
