How was a cooperative a structural challenge to the private factory model?

Correct answer: It placed shared ownership and distribution of gains instead of owner centered profit

A cooperative differs from a private factory because ownership and decision-making are shared more broadly among the members, often including the workers. Instead of one private owner keeping the main profit, a cooperative can distribute gains according to agreed rules and use them for the benefit of its members. It may also allow participants to have a greater voice in managing production. This challenges the usual owner-worker relationship at a structural level.

Option A correctly identifies shared ownership and distribution of gains as the key difference. A cooperative is not a system for refusing workers wages, reviving feudal dues, or placing production under palace control. The precise legal form of a cooperative can vary, but the central educational idea is collective participation rather than owner-centred control. Therefore, A is the best answer to the question.
