The correct answer is C. A pronoun has the same function as a noun, within a sentence. So, the pronoun usually refers to people, things, or something that you can mention. On the other hand, prepositions indicate meanings such as place, time, reason, relationship, among others. They do not refer to things or people like pronouns and nouns do. In fact, pronouns can be the object, that is complement, of the preposition.

A is the answer to your question.
<span>The correct option is option “C”. “I do not mind fishing, as
long as I don’t have to bait the hook” is the sentence in which the clause is
used as an adverb. The options “A” and “D” cannot be the right answer since in
both the cases the clause is modifying the subject and thus makes it an
adjective. So these two options are obviously ruled out. In case of option “B”
the clause is acting as a noun and so this option also gets cancelled out. </span>
