Answer:
B. Because it affects people's behavior and their lives
Step-by-step explanation:
Sociologists study the relationship between religion and social life because religions are phenomena of great relevance in people's lives, since they affect their behavior. People who are religious seek to live according to the set of beliefs and values of their religion. Thus religions serve as behavioral catalysts, positively or negatively affecting a person's happiness and well-being. For example, if a person commits acts that are considered sin by their religion, he or she will probably feel guilty and try to change their behavior. On the contrary, if the person can follow the dogmas he will feel good and will try to maintain the behavior.
