Solution
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.
The sentence expresses the mood of what is to be done.
Option A is correct because the word "should " according to the given sentence expresses that a person is supposed to face certain consequences if he or she doesn't work hard.
Whereas, option B expresses the mood of less possibility, option C expresses the mood of ability and option D expresses the mood of stronger assurance and what must be done. Therefore none of these moods fit in the sentence.
