Correct option is A
Article 243D(3) of the Constitution provides for reservation of seats for women in Panchayati Raj Institutions (PRIs). This article mandates that not less than one-third (including the number of seats reserved for Scheduled Castes and Scheduled Tribes) of the total number of seats in Panchayats shall be reserved for women, and these seats shall be allotted by rotation to different constituencies in the Panchayat.
Article 334 pertains to the reservation of seats for Scheduled Castes and Scheduled Tribes and the representation of Anglo-Indian communities in Parliament and State Assemblies. This does not relate to the reservation of seats for women in Panchayati Raj institutions, hence the second statement is incorrect.
