Final answer:
A subculture differs from a counterculture in that it exists as a smaller group within a larger society and may seek some changes while still adhering to most mainstream norms, whereas a counterculture actively opposes and seeks to replace those norms.
Step-by-step explanation:
The difference between a subculture and a counterculture is primarily in their relationship to the dominant or mainstream culture. A subculture is a smaller cultural group within a larger culture, where people share specific identities or traits but are still part of the larger culture. They may want to change certain aspects of the larger society but still follow established procedures. Counterculture, on the other hand, actively opposes and rejects some of the norms and values of the larger culture, often developing their own set of rules and norms and may seek to install their own values in place of mainstream ones.
From the given options, the correct answer would be (d) - both are distinct from mainstream culture, but a counterculture actively opposes important aspects of the mainstream. This is because counterculture members not only differentiate themselves from the larger society but also challenge and seek to change it.a
