Choose the correct singular, third person, conjugation of the verb to be in the future perfect tense.
A. You have been
B. I will be
C. She will have been
D. They will have been
is it D?
No. That's in the future perfect, but it is not singular.
So it's A?
singular = one person or thing
third person = not I, you, or we
future perfect = has "will have" for helping verbs
In D, "they" is plural. Which sentence has the singular third person?
