Equal pay for equal work is related to which principle?

Correct answer: Gender equality

The direct answer is B, gender equality. The principle of equal pay for equal work says that people doing work of equal value should receive equal wages without unfair discrimination based on gender. Step by step: compare the work and its value; if the work is equal, the payment should be equal; if women receive less only because they are women, that is wage discrimination; equal pay challenges that discrimination and supports gender equality. Option A, division of work, means distributing tasks and does not itself guarantee equal wages. Option B is correct because equal wages are a basic expression of fairness between genders. Option C, work leave, concerns absence from work and has no direct meaning here. Option D, household responsibility, concerns domestic duties and does not define wage equality. Memory cue: equal work plus equal wage equals equality.
