Which of the following is the most realistic goal for attaining better resilience?

a)let myself feel sad and then find ways to move on
b)give up drinking caffeinated drinks so i can relax more
c)study hard for exams so i don't disappoint myself or others

I believe (A) because to be able to be more resilient you have to experience sadness or some sort of difficulty that may have put you down, this will then challenge you to find ways to move on and create positivity in your mind to keep you going instead of giving up hence will make you resilient and persistent in any difficulties you face.
