Learn English – He…his boss that he…back after his vacation. Which answer fits the blank

future-tense

I am interested in this sentence:

He ______ his boss that he ______ back after his vacation.

a) doesn't tell / hasn't come

b) won't tell / won't have come

c) isn't telling / doesn't come

d) hasn't told / won't be coming

e) didn't tell / hadn't come

I've answered B but it's obvious that we can't have a sentence with two auxiliary verbs "to be" in the future form. But the right answer is D and I'm curious about the secont part. Since won't be coming is the future continuous tense I find no way of implementing it in this sentence, Am I mistaken? What way of usage the future continuous is it?

Best Answer

d) is the answer. 'won't be coming' is the same as 'isn't going to come back' or 'isn't coming back' - something planned.
