Will make brainliest and I need help ASAP!

Because Diana did not make the swim team this year, she wants to spend the year building her skills. Which of the following can best help her prepare for a stronger tryout next year?
A- Look for areas where she is stronger than other team meme era and practice to be even better.
B- Film herself swimming to locate areas she can improve her technique for better performance.
C- Take a few months off and then get back in the pool to work as hard as possible to build stamina.
D- Plan to talk with the coach about her times and why they were not good enough for her to make the team.
