IDIOMS — Choose the option that best expresses the meaning of the underlined expression in context. Sentence: 'Mohan always keeps himself to himself.'

Introduction / Context:
The phrase “keep oneself to oneself” is a British-leaning idiom describing a person who is private, reserved, or unsociable—someone who does not mix freely with others or share much about their life. The sentence asks you to capture that social behavior accurately.

Given Data / Assumptions:

• Subject: Mohan, in a general habitual description (“always”).
• Target trait: social withdrawal or privacy.
• We need the closest restatement without adding moral judgment.

Concept / Approach:
“Unsociable” expresses reluctance to engage socially; it is the neutral-to-slightly-negative label for the described behavior. “Selfish” involves putting one’s interests first at others’ expense, which is not implied. Being “too busy” is situational, not a personality trait. “Does not take sides” describes neutrality in disputes, not social reserve.

Step-by-Step Solution:
1) Identify idiom and register.2) Map to social trait: private/unsociable.3) Select “Is unsociable.”4) Exclude options that shift to motives or conflict positions.

Verification / Alternative check:
Paraphrase works: “Mohan is unsociable.” The habitual adverb “always” fits the idea of a consistent trait.

Why Other Options Are Wrong:
A) “too busy” is a temporary condition.B) “selfish” imputes moral blame absent in the idiom.D) “does not take sides” is about disputes, not sociability.

Common Pitfalls:
Projecting motives (selfishness) into neutral idioms about privacy. The phrase concerns engagement level, not ethics.

Final Answer:
Is unsociable
