The correct answer is D. Zila Kachahari Sachiva.
The Panchayat Institutions are the three-tier system of local self-government in India. The three tiers are:
- Gram Panchayat (village council)
- Panchayat Samiti (block council)
- Zila Parishad (district council)
The Chairperson of the Gram Panchayat is called the Mukhiya. The Chairperson of the Panchayat Samiti is called the Pramukh. The Chairperson of the Zila Parishad is called the Adhyaksha.
The Zila Kachahari Sachiva is the Chief Executive Officer of the Zila Parishad. He/She is not the Chairperson of the Zila Parishad.
Therefore, the wrong match is D. Zila Kachahari Sachiva.
