Question

Fill in the blank with the most appropriate word.

She's good ________ singing.

• A. on
• B. at
• C. in
• D. with

Answer 1

Answer: (B)

at

A preposition is a word which comes before a noun or a pronoun and establishes a relationship between the elements of a clause or words. Option B)at is correct as it indicates a skill. The other options are wrong as on, in, and with indicate a surface, inside something, and inclusion respectively. These uses don't fit in the given question. The correct answer is B)at.
