• A. to say
• B. say
• C. will I say
• D. saying

Answer 1

The correct option is A to say

Answer : C

Reading the sentence in the question, we understand that here to focus is on the agent (i.e. the person doing the action) -- here " I ".

According to grammar rules, the active infinitive form of the verb is used.

A verb is converted to it's infinitive form by adding "to" before the base form of the verb. Therefore, the infinitive form of the verb "say", is "to say".

Thus, the correct complete sentence is:

I didn't know what TO SAY.
