I guess they're looking for answer D, even though it's not strictly the only possibility.  The music player and the browser are both tasks, so it has to be a multi-tasking system.  And since no other user is mentioned I assume they are talking about a single user system even though a multi-user system would also be capable of multi-tasking.
