Question

Fill in the blank with a suitable preposition:

The teacher was disappointed _________ the work of the class.

• A. At
• B. On
• C. For
• D. With

Answer 1

The correct option is D 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 D)with is correct as it indicates a cause. The other options are wrong as at indicates a specific location, for indicates a purpose, and on indicates a surface of something. These uses don't fit in the given question. The correct answer is D)with.
