The correct option is B The number of reserved seats is decided by voting in both the Houses of the Parliament
Some sections of society have historically been marginalised, socially and economically. Therefore, to provide equal opportunity to these sections, certain constituencies are reserved in an election. This ensures adequate representation, in line with the democratic vision of the country. The Lok Sabha has 84 seats reserved for the Scheduled Castes and 47 seats for the Scheduled Tribes. The number of seats allotted to them is proportional to their population relative to the total population of the country.
