The correct option is A Sexual division of labour
Women continue to experience significant discrimination related to their participation in public and political life in most domains of the public sphere and in all geographical regions. A balanced sex ratio is desirable. Gender imbalances have been known in human history to cause serious negative consequences for society in long run. According to the Inter-Parliamentary Union, 2017 worldwide female representation rate is 23.6%. The sexual division of labour is the delegation of different tasks between male and females. It is because women have to face many obstacles and challenges in representing and administration, so participation in women's parliament has been limited.
