which sentence uses prepositional phrases to add variety and interest to its meaning?

D. With a sudden grunt, the spaniel leaped up after the wily chipmunk.

Explanation:

First of all, let's see what a prepositional phrase is. It is a phrase (a combination of at least two words) that consists of a preposition and a noun/noun phrase. In the sentence above, there are two prepositional phrases: with a sudden grunt (with + a sudden grunt) and after the wily chipmunk (after + the wily chipmunk).

Sentence C could also be correct here as there are two prepositional phrases there as well; however, it also uses a dependent clause which was not specified in the question.

an expression designed to call something to mind without mentioning it explicitly; an indirect or passing reference.

- "a nonrestrictive clause functions as a modifier to a noun (that is an object, person or concept). these clauses can be described by the following three options: it is set off by comas, it contains a subject and a verbs and it adds nonessential information to the sentence.

for example, in "here is bill gates, who confounded microsoft software company" we can identify "who confounded microsoft software company" as a nonrestrictive clause modifying the noun bill gates. this clause can be describes as a nonrestrictive clause because it is separated by a comma, it adds nonessential information to identify who bill gates is and it must contain both a subject (who) and a verb (confounded)."
