Question

Select the appropriate preposition.

Silkworms feed _____ mulberry leaves.

• A. on
• B. of
• C. at
• D. with

Answer 1

The correct option is A on

Prepositions are words that indicate relationships with the other words in the sentence.

'On' here is the right choice of preposition as it means 'on top of' and indicates that the silkworms feed on top of leaves.

Other options are not relevant in the given context, 'of' expresses a belonging, 'at' expresses a spot/place, 'with' means accompanied by. Therefore options B, C, D are incorrect.

Correct answer is option A.
