I would say the healthiest person both mentally and emotionally would be answer choice B. I would choose this answer because he does not need other people's approval like Elliot needs and does not need to feel liked and popular like Anna does. Chris is happy and does what he likes to do and his friendships are a healthy relationship.
The correct answer would be B, Chris takes tennis lessons and hangs out with friends after finishing his school work. He gets good grades, enjoys tennis and has strong bonds with his friends.
Explanation:
Being mentally healthy means your mind is fast and you are able to understand things quickly. You remember things, you are intelligent enough. Being emotionally healthy means you are capable of making bonds with people, you are emotionally attached to people around you. So Chris is the one who is both mentally and emotionally healthy. He plays sports, he comes out with flying colors and has strong friendship bonds.
