Choose the option that fills the blank with the most suitable word:

He worked for them ____ gratitude.

• A. on
• B. at
• C. with
• D. after

Answer 1

Answer: (C)

with

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 C)with is correct as it indicates description. The other options are wrong as on, at, and after indicate a surface, a specific location, and sometime later respectively. These uses don't fit in the given question. The correct answer is C)with.
