You should take a deep breath
The only correct option here is B. tragedy exposes negative emotions and fears. A is incorrect because this refers to comedy, not tragedy. C is incorrect because tragedies are usually sad throughout - there isn't much happiness there. D is incorrect because it almost never ends well.
