B) As we were walking to the county fair, the man told us that we were going the wrong way.

C) I asked the stranger if we were going the right way, and he told us that we weren't.

D) The stranger told us that we were going the wrong way.

A) The man, whose name I don't recall, told us that we were going the wrong way.

Explanation:

A relative clause is a dependent clause that modifies a noun. The clause whose name I don't recall is modifying the noun "man", so it is a relative clause.

A relative clause is introduced by a relative pronoun, a relative adverb, or a zero relative.

The clause whose name I don't recall is introduced by the relative pronoun whose.

The clause whose name I don't recall is set off by commas because it is a nonrestrictive clause (i. e. a clause that contains nonessential additional information)

The correct answer is: A) The man, whose name I do not recall, told us that we were going the wrong way. Relative clauses are used to define what person or thing is being talked about. They provide additional information or complete an idea that is not well understood in the previous sentence. They can be: anaphoric or cataphoric. In this case it is cataphoric with the relative pronoun whose indicating possession or link.
