The correct answer for the inclusion of the entry "Public Health and Sanitation" in the Constitution of India is option 2, which is the State List.

In the Indian Constitution, there are three lists: the Union List, the State List, and the Concurrent List. The Union List contains subjects on which only the central government has the authority to make laws. The State List contains subjects on which only the state governments have the authority to make laws. The Concurrent List contains subjects on which both the central and state governments have the authority to make laws.

Public health and sanitation fall under the jurisdiction of the state governments, as they are responsible for the implementation and management of healthcare services and sanitation measures within their respective states. The central government has limited involvement in these areas and mainly provides support and guidance to the state governments.

Therefore, the inclusion of "Public Health and Sanitation" in the State List of the Constitution of India reflects the responsibility of the state governments in regulating and ensuring the well-being of the public in matters of health and sanitation.
