Question

Complete the sentence using the most appropriate option:

A friend of yours offers you a lift in his car but you decide to walk.

You say: Thank you but _________________.

• A. I think I have walked.
• B. I think I'd walk.
• C. I think I'll walk.
• D. I think I am walking.

Answer 1

The correct option is C I think I'll walk.

The simple future is a verb tense that’s used to talk about things that haven’t happened yet, here, walking. We use the simple future to talk about an action or condition that will begin and end in the future. The formula for the simple future is will + [root form of verb], that is, will walk, or, I'll walk. Hence, Option C is correct.

The rest of the options do not express this condition.

Option A states an action that has already happened.

Option B states an unreal action: 'would' refers to a condition.

Option D states a present action in the continuous from.

Hence these options are incorrect.
