Which of the following options can replace the following expression?A…

The correct answer as per the official NTA Answer Key is Option (2) → B and D only

Note: The given answer is as per the official NTA Answer Key. However, none of the given words means "a person who steals, especially secretly and without violence"; that is the meaning of thief, which is not among the options. NTA's pair "intruder" and "trespasser" is the closest, because both describe a person who enters a place without permission and without force, but neither word includes stealing.

(A) Treacherous — Incorrect. Treacherous is an adjective meaning disloyal, likely to betray trust, or dangerous (a treacherous road); it is not a person and has nothing to do with stealing.
Example: The treacherous general sold the secrets to the enemy.

(B) Intruder — Incorrect. An intruder is a person who enters a place without permission, often secretly; he may or may not steal.
Example: The guard caught an intruder climbing over the wall.

(C) Robber — Incorrect. A robber is a person who steals by using force or threats; this goes against "without violence".
Example: The robber threatened the cashier with a knife.

(D) Trespasser — Incorrect. A trespasser is a person who goes onto someone else's land or property without permission; stealing is not part of the meaning.
Example: The sign warned that trespassers would be fined.
