Question

By this time tomorrow I ... for three hours. A)will fly B)will be flying C)will have fly. D)will have been flying

Answer 1

By this time tomorrow I will have been flying for three hours.

Answer 2

The correct answer is B) will be flying.

The phrase "will be flying" indicates that the action of flying will be in progress at a specific time in the future (tomorrow). This is the most appropriate choice to complete the sentence.

Option A) "will fly" implies a simple future action, without any indication of duration, and it does not match the time frame indicated in the sentence.

Option C) "will have fly" is grammatically incorrect, as "fly" is an irregular verb and the past participle form is "flown".

Option D) "will have been flying" implies a duration of time leading up to the specific time mentioned in the sentence (tomorrow). While it is grammatically correct, it implies a longer duration of time than the simple future action indicated in the sentence.
