• D. None of the above

Answer 1

The correct option is D None of the above

The tense of a sentence denotes a time, whether it is the time now (present), time then (past) or the time to come (future). The verb of a sentence has most to do with the tense. The Future Perfect Continuous Tense describes an action that is still continuing even after a certain point of time in the future. The group of verbs (one or more helping verbs and a main verb) is of the form will have been + present participle (verb + ing), this form is used in a positive statement, they change slightly when the statement becomes negative or interrogative. The negative sentence is formed by adding 'not' after the first helping verb 'will', like in option C. An interrogative statement is formed by interchanging the positions of the subject 'you' and the first helping verb 'will', as seen in option B. Options A, B and C are all in the future perfect continuous tense, A being an affirmative, B being an interrogative, and C being a negative. We need to choose an option that is not in this tense, and all these sentences are of this tense, hence A, B and C are incorrect and option D is correct.
