Which word means necessarily or demonstrably true; impossible to deny or disprove?

• A. Incontrovertible
• B. Irrefutable
• C. Intimation
• D. Ossify

Answer: (A)

The main idea is a word for something that cannot be denied or disproven—it's indisputable and beyond challenge. Incontrovertible fits this sense exactly: it describes a fact or claim that is so well supported or so clear that there’s no real way to argue against it. It carries a sense of finality and firm certainty. Irrefutable is very close in meaning, often implying that evidence makes refuting it impossible, but incontrovertible emphasizes that the conclusion itself is beyond dispute. The other two options don’t fit. Intimation means a hint or suggestion, not a guarantee of truth. Ossify means to harden or become rigid, literally or figuratively, and has nothing to do with being undeniable.
