A homophily is term that is used in Sociology (the study of society and its people). This term refers to people's tendencies to identify and connect with people who are much like themselves. They can be similar in gender, race, socioeconomic status, personality, interests, or in their belief systems.
Example "A" would not best exemplify homophily because the statement does not provide any information that we would identify as commonalities.
Example "B" also is not an example of homophily, for the same reasons stated in Example "A".
Example "C" is a very good example of homophily. These two young people are the same race (race), attend the same church (belief system), and are majoring in the same discipline (interests). 
Example "D" is another poor example of homophily. Although the pair met at a funeral (they know common people) and share common interests, their differences are a longer list than their commonalities. They are very far apart in age, have different religions (belief system), and are from different classes (socioeconomic status).
 
        
             
        
        
        
Answer: Experimental Method
Explanation:
The field of psychology has several research methods for the study of human behavior and its different forms. There is what is called experimental psychology, which expresses that psychological phenomena can be studied through the experimental method through observation, manipulation, and recording of the variables that affect the object of study.
The experimental method expresses that one or several variables are manipulated to determine their effect on an independent variable. In this case, rap music is set to see how it influences aggressive behavior and is analyzed because this type of music may have a certain relationship with the behavior.
In the experimental method, humans and animals are used to know the behavior that an individual may have when exposed to other variables that may interfere with their behavior. This type of experiment is usually done more in animals than in people because researchers can dispose of them at any time and in turn have more control. Besides, some experiments cannot be carried out in human beings due to ethical issues since if they are carried out they could put the person's health at stake.
