By the end of this month, _____ for years in this school?
Answer Details
The best option to complete the sentence is "I will have been studying for years in this school". This is because the sentence is referring to a future point in time, the end of the month, and the speaker is indicating that they will have been studying for some time up until that point. The correct option, "I will have been studying", is in the future perfect continuous tense, which is used to describe an ongoing action that will be completed at a specific point in the future.
