Select the most appropriate option to fill in the blank.
My neighbour has become dependent on drugs. He is a/an _________.

Correct option is B

The correct option to fill in the blank is (b) addict.
An addict is a person who has become physically or mentally dependent on a substance (like drugs) or a habit. Here, the neighbour is dependent on drugs, so “addict” fits both grammatically and contextually. (Hindi meaning: नशे का आदी / लती)
Example: He became an addict after using drugs for a few months.
Explain why other options are incorrect:
· (a) adamant: refusing to change one’s mind; very stubborn (हठी / अडिग)
· (c) derelict: in very poor condition; also a person who is homeless/neglected (जर्जर / बेसहारा)
· (d) edict: an official order or announcement (सरकारी आदेश / फरमान)
