5. in which sentence is the underlined verb in the future perfect progressive tense?
a)by the age of five, she will have visited new york city.
b) she will have been visiting new york city for a week when she turns five years old.
c)at the age of five, she will visit new york city.
d)she will be visiting new york city when she turns five years old.

I believe that the answer is B) She will have been visiting New York City for a week when she turns five years old.

The "will have been" part of the sentence, which is the third form of the verb, is what makes it future perfect progressive tense. Hope this helps!
