Answer 1

The question has to be tweaked, for a correct answer.

The Panchayat Samiti is the link between Gram Panchayat and Zila Parishad.

Panchayat Samiti is the local rural body at intermediate level, in the institution of Panchayati Raj. This body is the vital link between the village council or Gram Panchayat and the district board or Zila Parishad.

Panchayat Samiti operates at the Taluk level, governing villages of the Tehsil (jointly referred to as Development Block).
