Answer 1

The answer is the option C. The music teacher gave him a choice of horns - for example, the trumpet, the tuba or the saxophone, because it is correctly separating two main clauses; in this case the second clause contains and explanation of the first one. In the options A, B and C the dashes are splitting phrases that should not be split.
