Question

Complete the sentence with the correct form of the verb given in the bracket.
By this time tomorrow, I _____home. (reach)
A. would have reached
B. will have reached
C. shall have reached
D. will reach

Answer 1

Hint: ‘will' is used for affirmative and negative sentences about the future. Use 'will' for requests too. If you want to make an offer or suggestion with I/we, use 'shall' in the question form. For very formal statements, especially to describe obligations, use 'shall'

Complete answer:
We use 'shall' for the future perfect tense with first-person pronouns, I or we. While 'will' is used for second and third-person pronouns (he, she, it, they, etc.). We use (will or shall) + have + the third form of the verb. We use ‘shall’ for future time reference with pronouns ‘I’ and ‘we’.
Option A. ‘would have reached’ is the past perfect tense. It is used in conditionals to talk about something that did not happen in the past.
Option B. ‘’Will have” is used for simple future perfect tense or for something that will be already finished by the time some other work starts in the future.
Option D. I will reach is incorrect because it is in the simple future tense. So, the correct answer is option C.

Note:
Will have “is used for simple future perfect tense or for something that will be already finished by the time some other work starts in the future. The action is going to happen in the future ”Would have” on the other hand refers to a past event or something that would have finished the time something else started in the past.
