why does casey want to meet with alex?

to help casey prepare for the job interview
to introduce casey to the hr representative

Explanation:

In the email, Casey says "I would like to meet with you to determine your interest in this possible career move. In our meeting, we can discuss salary and the specific responsibilities of the Level 2 role. Please come prepared with any questions you may have about the promotion." The Level 2 role is the supervisor role Alex aspired to. The other options: there's no mention of explaining the open position reason, Casey is the manager (not preparing for an interview), and no mention of introducing to HR. So the correct option is "to discuss the supervisor role and answer questions".

Answer:

to discuss the supervisor role and answer questions
