Question

Fill in the blank with the appropriate form of the verb:

What __________ if you were to win a lottery?

• A. will you do
• B. will you have done
• C. would you do
• D. would you have done

Answer 1

The correct option is C would you do

The subjunctive mood is used in subordinate clauses and refers to unreal or improbable present or future situations.

The given sentence requires the sentence to be in past form and the past form of 'will' is 'would' and 'would' is used as a modal verb to indicate a conditional or subjunctive mood. Thus, according to the rules, the correct answer will be Option C. The other remaining options are incorrect.

Option A, B and D express different moods.
