## Core Concept
The Anganwadi worker plays a crucial role in the implementation of the Integrated Child Development Services (ICDS) program in India. The ICDS aims to provide nutritional and educational support to children and their mothers. Given the importance of their role, it is essential to have a supervisory structure in place.

The correct answer, **Supervisor or Auxiliary Nurse Midwife (ANM) or Community Health Worker**, is responsible for overseeing the work of Anganwadi workers. Typically, an Auxiliary Nurse Midwife (ANM) or a supervisor designated by the local health department looks after the work of Anganwadi workers. They ensure that the services provided by the Anganwadi centers, such as immunization, nutrition, and pre-school education, are delivered effectively and according to the guidelines.
