The Panchayati Raj system in Mizoram has two tiers: the village panchayat and the district panchayat.
The village panchayat is the lowest tier of the Panchayati Raj system. It is responsible for the development and welfare of the village. The village panchayat is elected by the people of the village.
The district panchayat is the second tier of the Panchayati Raj system. It is responsible for the development and welfare of the district. The district panchayat is elected by the people of the district.
The Panchayati Raj system in Mizoram is a democratic system of governance. It is designed to give power to the people at the grassroots level. The Panchayati Raj system has been successful in bringing about development and welfare in the villages and districts of Mizoram.
The other options are incorrect because they do not reflect the actual number of tiers in the Panchayati Raj system in Mizoram.
