I'm having some trouble on this.

Answer 1

There are three prepositional phrases that modify nouns and thus are adjective phrases.

I'll be glad to check your answers.

Answer 2

Yes. C has an adjectival phrase. B has two adjectival phrases.

b. The fastest land mammals, cheetahs, reach speeds in excess of 65 miles per hour.

in excess modifies speeds
of 65 miles per hour modifies excess

Answer 3

So, both B and C would be acceptable?

Answer 4

And, isn't excess a noun in this case?

Answer 5

Yes, both B and C are correct. Excess is a noun.

Answer 6

And one more in B. per hour is an adjectival phrase modifying hour.
