The status and treatment of women varied widely across different regions and communities. While some women might have held respected positions, overall, the status of women in medieval society was often influenced by cultural, social, and religious factors.

The statement "They were allowed to study the Vedas" is not correct Access to education and the study of religious texts, including the Vedas, was limited for women during this time. Educational opportunities for women were often restricted, and the ability to study sacred texts was not common.

The statement "Polygamy and ‘purdah’ system were prevailing in society" is correct  Polygamy, the practice of having multiple spouses, was more prevalent among the elite and ruling classes. The 'purdah' system, involving the seclusion of women from public view, was also a common practice in certain communities.
