Correct option is C
Addressing gender stereotypes in classrooms involves challenging and breaking down preconceived notions about gender roles. This can be achieved by presenting examples and scenarios that go against these stereotypes, thereby encouraging students to think critically about gender norms. Restricting cross-gender interactions or avoiding discussions on gender discrimination would reinforce stereotypes rather than challenge them. Hence, the correct approach is to present counter-examples that question and dismantle gender stereotypes, fostering an environment of equality and understanding among students.
