Select the most appropriate meaning of the given idiom. Hit the nail on the head

Correct — D. Hit the nail on the head means to say exactly the right thing, to identify or describe a matter precisely.

The head in it is the nail's head: strike that squarely and the nail goes straight in, and the picture carries over to a remark that lands exactly on the point.

Option (d) states that reading — they have accurately identified or explained something.

Why the others are wrong

• (a)
  They hit a nail with a hammer. — The literal reading, a hammer and a nail. An idiom does not mean the sum of its words, and the picture it draws is a hint towards the meaning, not the meaning.
• (b)
  They are experiencing a headache. — Built from the stray word head. The idiom has nothing to do with pain, and the head in it belongs to the nail rather than to a person.
• (c)
  They're uncertain about a decision. — Uncertain reverses the idiom. Hitting the nail on the head praises precision, so an option about wavering over a decision says the opposite.

Idioms are fixed and non-compositional — the words cannot be added up. You either know the phrase or you reason from the image it draws, and the image only points.

The wrong options here follow a familiar pattern: one translates the phrase literally, one reverses its sense, and one is built from a single word lifted out of it.

The carpentry image, a clean square blow, points at accuracy, and accuracy is what the idiom means.
