Fill in the blank with a proper modal so that the sentence sounds like a promise.

I _________ help you.

will

The correct answer is Option (4) - will

• "Will" is the appropriate modal to express a promise or commitment to do something. In this context, it clearly conveys the speaker's intention to help.
• I will help you.

• "Might": Indicates possibility, not a definite promise.
• "Shouldn't": Negative modal that implies prohibition or advice against doing something.
• "Can": Indicates ability but does not convey a promise.
