Modal Verbs show us the attitude of the speaker to what is being said or done. The term "modal" means expressing mood and mood is a way to express the attitude of the speaker.

Option C is the correct answer because it has a sense of obligation.

Whereas, option A is applied in future tense with an expression of certainty; option B also expresses certainty but with lesser probability; and option D expresses lesser chances of possibility.
