Question

Fill in the blank with the most appropriate word:
I met my classmates ______ the party.

• A. in
• B. since
• C. on
• D. at

Answer 1

The correct option is D at

Answer : D

Prepositions are words that are used to show relation of a noun to another element (noun/adjective/verb) in the sentence.

Let's take a look at the options:

• in : It is used to mean "inside"
• since : It is NOT a preposition of Place
• on : It is used to refer to the placement of something over something else
• at : It is used to refer to an exact location/event where something is situated/happened

On reading the sentence in the question, we understand that the speaker me his classmates at a specific location / event, i.e. the party.

Therefore the most appropriate word here is "at".

Thus, the correct complete sentence is:

I met my classmates AT the party.
