Expectation that daughters do household work and sons do outside work strengthens which idea?

Correct answer: Gender stereotyped division of work

When a family expects daughters to do household work and sons to do work outside the home, it assigns duties according to gender rather than individual ability, interest, or choice. Such expectations are learned through family and society and can limit the education, mobility, skills, and career opportunities of girls. They can also make boys feel that domestic care is not their responsibility. This pattern treats certain jobs as naturally suitable for one gender, even though all people can learn many kinds of work.

Option A is correct because this is a gender-stereotyped division of work. It is not equal opportunity, since the two children are not being offered the same choices. It is also not skill-based selection, because no assessment of ability is made. Age-based training would concern stages of development, not whether someone is a boy or a girl. A fairer arrangement shares household tasks and provides education and work choices without restricting them by gender.
