Question

Choose the appropriate preposition and fill in the blank:

I was not in when you phoned. I was my sister's house.

• A. on
• B. at
• C. with
• D. in

Answer 1

Answer: (B)

at

The given sentence speaks about the subject's specific location. Therefore 'at' is the suitable answer, since 'at' is used to describe a specific place or location. Thus option B is correct. On the other hand 'on' is used to describe about something above , hence option A is incorrect. The preposition 'with' is used to denote a company or presence of something or somebody while 'in' is used to describe a position within or inside something. Since the sentence speaks about a specific location of the speaker , 'with' and 'in' are unsuitable in the given context. Thus option C and D are incorrect.

Thus the complete sentence becomes: I was not in when you phoned. I was at my sister's house.
