Answer:
What "selection"?
Explanation:
You just said "The selection"
The complete adjective clause in the sentence is F. that I have prepared.
An adjective clause usually starts with who, whom, when, where, why, that or which. Most often it provides more information and description; however, it will not change the meaning of the sentence.
A dependent clause adds something to a sentence but cannot be a standalone sentence, hence "dependent." In this sentence, "when I had... phone" is a dependent clause.
