Question

Choose the correct word or phrase that completes the sentence correctly.

These animals feed ____ grass.

• A. with
• B. on
• C. in
• D. for

Answer 1

Answer: (B)

on

A phrasal verb is a phrase that consists of a verb (feed) with a preposition (on) or adverb or both, the meaning of which is different from the meaning of its separate parts.

Option B 'on' is the correct answer because it correctly forms the phrasal verb 'feed on'. If an animal feeds on something, it eats it, especially as its usual food.

Options A, C and D are incorrect because none of these prepositions can be used with the verb 'feed' to form the correct phrasal verb.
