When managing emotions, all of the following are examples of protecting your health except sitting alone in the cafeteria at lunch.
Although I was stuck on option D and option C, the most reasonable answer is the last one. Sitting alone in the cafeteria can have an affect on your mood which is not healthy (unless somebody likes sitting alone). Why I was considering the option 'meeting friends to play basketball', I thought of the risk of getting injured. Since we are talking about managing emotions here, playing basketball with your friends might be quite fun for your mood.
