The correct answer is: won’t be.
The sentence is in the future tense, so we need to use a future tense verb. The verb “be” has several different forms in the future tense, depending on the context. In this case, we need to use the “will be” form.
The other options are incorrect because they are not in the future tense. The verb “haven’t be” is in the present perfect tense, the verb “aren’t be” is in the present tense, and the verb “didn’t be” is in the past tense.
