Identify the prepositional phrase in the sentence below.

I researched my report on the Internet.

a. on the Internet

c. I researched

b. the internet

d. my report

Answer : a. on the Internet

On the Internet is the prepositional phrase on the sentence above because it is made up of the preposition "on" and the object "the internet". It also answers the question "which one". It should be noted that a prepositional phrase should not contain the subject of the sentence which means "I researched" is not a prepositional phrase and so with the internet and my report as they are both nouns with article and a pronoun.
