I will also agree that B: The man <em>whose </em>wallet Jan found gave her a reward.
<u>Characteristics of Adjective clause:</u>
First, the sentence must have a verb and a subject.
Second, it must have a relative pronoun (i.e. that, which, whose, whom, and who) or relative adverb (why, where, and when). If you notice, the relative pronouns in a round about way refers to someone or something. For example, who does the wallet refer to? It refers to the man. The relative adverbs as you can tell answer question words.
<u>Pattern to look for:</u>
<u />Sometimes it is tricky to find clauses.
With Relative Adjectives there are a couple of things to look for.
The beginning should start with a relative pronoun or relative adverb then add a subject and finally add a verb: RP (or RA) + S+ V= relative adjective clause
Another formula for finding a relative adjective is Relative pronoun acting as the subject with a verb added: RP as S + V.
Hopefully this helps and good luck.
