What evidence best supports the conclusion that living in the court gave women greater freedom?
O Women serving in the Palace are bound to be ...
wicked."
O "After all, women at Court do not spend their time
hiding modesty behind fans and screens.
"Small wonder that the young men regard them as
immodest."
*They are not exactly bashful when it comes to
looking at the great people in the Palace

B. After all, women at Court do not spend their time  hiding modesty behind fans and screens.

Explanation:

'The Pillow Book' is a book written by Sei Shōnagon. The book was written when Sei was serving as a court lady in the courts of Empress Consort Teishi.

The statement that best supports the idea that the court gave greater freedom to the women is in option B. Here Sei Shonagon talks about Service at Court and narrates that men saw women in courts or palace with prejudice perceiving them to be wicked. It is because the courts gave them freedom to look at men face-to-face without fear or hesitation.

Therefore, option B is correct.
