Which of the following can be a source of gender inequality and discrimination in society?

Correct option is A

Assigning different values for the work of women and men is a source of gender inequality and discrimination in society. This often manifests in the form of unequal pay for equal work, undervaluing work traditionally or predominantly done by women, and societal attitudes that perceive men's work as more valuable or important. The other options - provision for girls’ education, curtailing dowry practices, and separate washrooms for boys and girls in schools - are generally measures aimed at reducing gender inequality and discrimination, not sources of it.
