The correct answer is B. get up.
The verb “get up” is used to describe the action of rising from a lying or sitting position. It is typically used in the present tense, as in “I get up at 7:00 a.m. every day.” In this case, the sentence is about a habitual action, so the present tense is the most appropriate tense to use.
The other options are incorrect because they are not in the present tense. Option A, “got-up,” is in the past tense. Option C, “gets up,” is in the third person singular present tense. Option D, “is get up,” is not a grammatically correct sentence.
In conclusion, the correct answer to the question “My parents . . . . . . . at 5:30 a.m daily” is B. get up.
