Which of the following concepts refers to social norms that dictate the acceptable reasons for engaging in relationships with others?

The concept that refers to social norms dictating the acceptable reasons for engaging in relationships with others is mate selection. This term encompasses the various criteria and social guidelines that influence individuals in choosing their partners. These criteria can be influenced by cultural, social, and personal factors, shaping how relationships are formed, maintained, and perceived within a specific society.

Endogamy specifically refers to the practice of marrying within a specific social, economic, or ethnic group, which is just one aspect of mate selection. It is a more constrained subset of the broader concept. Social taboo refers to prohibitions against certain behaviors, which may impact relationships but does not specifically address the norms around choosing partners. Sexual norm encompasses attitudes and expectations related to sexuality, which may overlap with mate selection but does not solely define the parameters for entering relationships.
