Most students of this class are intelligent select the alternative below that follows from the above statements.

Read this as a logical inference, not as a fact about real students. "Most students of this class are intelligent" means more than half are intelligent, and that necessarily means at least some are. So D follows directly.

• A is wrong: "Most" does not say that none are unintelligent. It leaves room for a minority who are not intelligent, so A goes beyond the statement.
• B is wrong: The statement says nothing comparative about the remaining students. Calling them "less intelligent" adds a claim that is not given.
• C is wrong: This is the same overreach as A. "Most" is not "all".
• D is correct: It is the weakest claim the statement guarantees, and it is the only option that must be true if the premise is true.

Core concept: quantifiers in statement-and-conclusion reasoning. "Most" implies "some" but never "all". The same discipline helps in Mains argument analysis, where you must separate what the evidence supports from what it merely suggests.

Trap: Aspirants pick A or C by reading "most" as "almost all", which is a practical reading rather than the logical one.
