Question

Fill in the blank with a suitable option:

Your umbrella is wet. It ___________ raining.

• A. Must be
• B. Was
• C. Can't be
• D. Might

Answer 1

The correct option is A Must be

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 A is correct as wet (complete possibility) indicates the use of must be.

The other options are wrong as no other modal can be used here.

The correct answer is A) must be
