What Was Christine De Pizan's Explanation for Why Girls Appeared

What was Christine de Pizan's explanation for why girls appeared less intellectual than boys?

A) Women were more spiritually minded than men and, therefore, had less interest in secular matters.
B) If daughters were sent to school, then they would learn as much as sons, and they would be as intellectually competent as boys.
C) Teachers paid less attention to girls than boys in the classroom; therefore, it seemed that girls were less engaged.
D) There was no discrepancy in learning; the notion that girls appeared less intellectual was manufactured by male critics.
E) Since there were so few female teachers, girls naturally appeared reluctant to speak.
