The correct answer is - women being prevented from voting.
Even though India has had a very long history of class segregation, as well as gender segregation, that has dramatically changed in the past few decades. The country is now a democracy, much more than the Western democracies even if we consider the daily lives and behavior of the people which is much less regulated and much more free.
The women are allowed to vote by law, and no one is allowed to strip them of that right. If someone tries to do such a thing than the law predicts big fines and charges. It is happening though occasionally on places that are still practicing the traditional life, mostly in the rural areas far away from the cities and towns, but it is becoming less and less practiced with each new generation.
