Question

Fill in the blank with a suitable preposition:

Switch _______ a light. It's getting dark.

• A. Of
• B. Off
• C. Out
• D. On

Answer 1

The correct option is D On

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 D)on is correct as it indicates a process. The other options are wrong as of, off, and out indicate possession, removal of something, and something away from the inside of an area respectively. These uses don't fit in the given question. The correct answer is D)on.
