A prepositional phrase is a group of words that lacks either a verb or a subject, and that functions as a unified part of speech. It normally consists of a preposition and a noun or a preposition and a pronoun.
This sentence has a compound subject.
A compound subject contains more than one subject - as you can see here, there are two subjects: Jason AND Raci, which makes this subject a compound one (made of at least 2 entities). Nothing else is compound in this sentence.
