Question

Fill in the blank with a suitable preposition:

Someone is waiting __________ the library.

• A. Through
• B. On
• C. Out
• D. Outside

Answer 1

The correct option is D Outside

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)outside is correct as it is used to indicate an area away from the inside of some place. The other options are wrong as though, on, and out means despite the fact that, indicate a surface, and absent respectively. These uses don't fit in the given question. Out and outside do indicate a location away from the inside but when the name of the place of which something is away from is given, we use outside rather than out. The correct answer is D)outside.
