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 Tense is used to describe an action that will finish by a certain point of time in the future. The verb or group of verbs in a sentence of this tense is of the form shall/will have + participle (verb form). From the options, Option C is in the Future Perfect Tense as it refers to an action "worked on this project" at a given point of time in the future "this time next week". We need to choose an option that is not in the future perfect tense, hence option C is incorrect. In options A and B, we see the form will have been + present participle (verb+ing), which is the form used in future perfect continuous tense, hence the sentences in options A and B are not in the future perfect tense, and these options are correct. Option D is incorrect because one of them (option C) is in the future perfect tense.
