Answer:
The correct answer is d.
Explanation:
In sociology, a subculture refers to a group of people within a larger culture that hold different ideas, values and ways of life than those of the mainstream, while still tied to their original culture. A counterculture is a type of subculture that holds different values and ideas that are directly and actively in opposition to important aspects of the mainstream. So while all countercultures are subcultures, not all subcultures are countercultures.
Some famous examples of countercultures were the hippie movement of the 1960s and the punks in the 1970s-1980s. They both explicitly rejected many aspects of the mainstream of the time and sought a lifestyle that directly opposed it.
