Answer:
D. Wei is bullying Alejandro.
Step-by-step explanation:
You can tell that Wei has bad intentions from the words "sneering" and "smirks". Because he is sneering at Alejandro, it is clear that he is talking in a mean and sarcastic way, not a genuine friendly way. From this, you can infer that Wei is not his friend, so it can't be B. Wei is Alejandro's friend.
Wei sizes him up and smirks, which shows that he believes he is stronger than Alejandro and questions him in an unfriendly way, which shows that he doesn't lack confidence, so it can't be C. Wei lacks confidence.
That leaves us with A and D. From the dialogue, it doesn't seem like Wei is asking for help, which leaves us with D. Wei is bullying Alejandro, which is shown through his rude remarks and actions.
