Final answer:
The student should choose option C, as Alex is excited to watch the movie collection because he appreciates the thoughtful gift.
Step-by-step explanation:
The subject of this question is English because it is asking about the motivation of a character in a story.
To determine the answer, we need to look at the options provided. Option A states that Alex is indifferent to the movies, which means he wouldn't be excited to watch them quickly.
Option B suggests that he wants to savor each movie slowly, so this is also unlikely. Option C states that Alex appreciates the thoughtful gift, which is a valid reason for being excited to watch the movies.
Option D states that he dislikes watching movies, but this contradicts the fact that he is excited to watch them all. Therefore, the correct answer is C. He appreciates the thoughtful gift.
