It is D .......................
Explanation:
Every human being has moments of ups and downs in life. The best moments are those lived with genuine joy and are usually the simplest moments, such as being with the family, watching the sea, laughing with friends, etc.
Negative moments can happen for several reasons, such as frustrations, regrets, anguish, etc., which must be dealt with wisely, calmly and most importantly, seek professional help when you feel you are entering a state of depression.
Darling, this is about you. You need to write something that happened to YOU. There's no way people on here can do this assignment for you or even try to help when it's this simple. I'm sorry, but don't you have anything you can reflect over? A homeless person, a friend who's parents were or weren't together? Just take some time and think about it.
