Trey repeated the scales. His manipulation of the keys was

becoming less of a struggle, and the tuba was making

sounds that were almost musical. The low notes still gave

him pause, though, so he attempted them again. After

countless repetitions, his room boomed with the tuba's

the answer is C.

Determined.

Explanation:

Trey doesn't show any signs of frustration - he is just determined and stubborn to learn how to produce certain sounds with his tuba. We also don't see evidence that he is talented - all we can see in this excerpt is that he is trying hard to learn how to do something. He is not impatient - as a matter of fact, quite the opposite is true. In the end, when his mother praises him, we know that his determination (or positive stubbornness) was successful. He wanted to learn how do to that with his tuba and he managed to after practicing.
