What Did Albert Cohen's Research into Delinquent Subcultures Reveal About

What did Albert Cohen's research into delinquent subcultures reveal about how criminals organize themselves and why?

A) Those who are unable to achieve middle-class goals develop their own culture with a set of roles, norms, and values within which they can succeed.
B) Young people develop relationships with other teens that have already been in conflict with the law and this frustrates police efforts to maintain law and order.
C) Criminals live in low-income neighbourhoods with other criminals and this forces the closure of businesses and any other legitimate means of income.
D) Criminals associate in cultural groups which allows them to have a larger voice in the mainstream culture.
