The correct answer is: B. Insurance.
Infrastructure is the basic physical and organizational structures and facilities needed for the operation of a society or enterprise. It includes the services and facilities necessary for the production and distribution of goods and services, the flow of people and goods, and the maintenance of health and welfare.
In India, infrastructure facilities include:
- Transportation: Roads, railways, airports, seaports, and inland waterways.
- Energy: Power generation, transmission, and distribution.
- Water supply: Water treatment and distribution.
- Sanitation: Wastewater treatment and disposal.
- Communication: Telecommunications, postal services, and broadcasting.
- Education: Schools, colleges, and universities.
- Health care: Hospitals, clinics, and other medical facilities.
- Housing: Residential buildings, commercial buildings, and industrial buildings.
- Public safety: Police, fire, and emergency services.
Insurance is not considered an infrastructure facility because it is a service that provides financial protection against losses. It is not a physical structure or facility that is necessary for the operation of a society or enterprise.
The other options, A, C, and D, are all considered infrastructure facilities because they are physical structures or facilities that are necessary for the operation of a society or enterprise.
