What is the strongest reason to consider compulsory education for girls a revolutionary reform?

Correct answer: It connected girls with state responsibility toward knowledge and opportunities.

The governing concept is that social reform can transform access to education and future opportunities even when it does not immediately create political equality. Compulsory education for girls treated their learning as a public responsibility rather than a private privilege available only to some families. It could improve literacy, confidence, employment prospects, and participation in public life. Thus option A is correct. Option B confuses education with suffrage; compulsory schooling did not instantly give women the vote. Option C describes neither the purpose nor the effect of the reform. Option D is the opposite of revolutionary change because restoring feudal dues would strengthen older obligations and privileges.
