The correct answer is: Option D. By referencing an ancient custom throughout her poem and expressing the sorrow it causes, the speaker makes the argument that it is time for India to change and develop its own modern identity.
The author poetically describes the physical appearance of women under the veil of this custom - focusing on the concealment of their faces.
It is depicted how other people are afraid to rebel against this tradition by lifting these veils in the verse "But though no hand unsanctioned dares...", and the author explicitly demonstrates the sorrow this inaction causes on her with the verses "And Sorrow looks into her face..." and "Or shield a woman's eyes from tears?"
