Answer:
She should learn a serve drill and ask a friend to help her practice after school at least three days a week.
Explanation:
This is the best option, because Danielle needs to practice her serve but in a controlled environment like an actual game, and that can be achieved with a simulation or serve drill. We need to remember that our body learn by repetition, using muscle memory, that is, forming a procedure in the memory that involves a motor task to muscles, which in this case is to serve.
On the other hand, practicing at least three days per week is proper, because that way she won't stress herself, which it's the worst result she could have.
