Question

In which sentence does the adjective "close" act as an adverb?

• A. They were close friends once.
• B. Great importance is given to the close bond between mother and child.
• C. They paid close attention to the investigation.
• D. They stood close to each other.

Answer 1

The correct option is D They stood close to each other.

In options A, B and C, "close" is an adjective that describes their respective nouns. In A and B, it describes the relationship or connection while in C, it describes the act of being careful ("attention"). Therefore the three options are incorrect.

In option D, "close" modifies the verb "stood" (stand), making it an adverb. Thus, option D is correct.
