She sells her pictures _____ the rate of five thousand a piece.

• A. by
• B. with
• C. at
• D. in

Answer 1

The correct option is C at

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)at is correct as it indicates an amount. The other options are wrong as by, with, and in indicate usage, inclusion, and the inside of an area respectively. These uses don't fit in the given question. The correct answer is C)at.
