Which of the following is an effect of structural sexism?

B is indeed the correct response because it highlights a significant consequence of structural sexism, which refers to the ways in which gender discrimination is embedded in the societal structures and institutions. Structural sexism manifests in various domains, including employment, where women often face penalties or biases related to expectations surrounding child-rearing. This can result in fewer opportunities for promotions, unequal pay, and overall career advancement hindered by the assumption that women will prioritize family over their professional responsibilities.

By contrast, the other options do not accurately reflect the influence of structural sexism. For instance, suggesting that men have an equal share of parenthood responsibilities overlooks the persistent societal expectations that typically assign primary caregiving roles to women. The complete elimination of gender stereotypes is an ideal that has not been achieved and does not reflect the reality of ongoing stereotypes that affect behavior and expectations. Lastly, although increased support for women's rights is a positive movement, it does not inherently result from structural sexism, but rather it exists as a response or challenge to it. Therefore, B correctly captures a real and impactful effect of structural sexism on women's professional lives.
