The correct answer is C. Differential association theory
Step-by-step explanation:
The differential association theory is a theory in sociology and criminology that proposes individuals can learn behaviors, beliefs, attitudes, etc. from others especially by interacting with them, which is used to explain criminal behaviors. Aubrey's mother is a supporter of this theory, because she believes Aubrey will be negatively influenced by Michelle and she might make negative decisions or make negative actions just because she interacts with Michelle, which shows the mother believes she beliefs, attitudes, etc. are learn or acquired by interacting with others as in differential association theory.
