Explanation

Let's assess the eradication status of each disease in India: 1. Diphtheria: While vaccination has significantly reduced its incidence, diphtheria has not been fully eradicated in India. Sporadic cases and outbreaks still occur, particularly in areas with low vaccination coverage. 2. Chickenpox: Chickenpox is a common viral infection that has not been eradicated in India. While a vaccine is available, it is not part of the universal immunization program aimed at eradication, and cases continue to be reported regularly. 3. Smallpox: Smallpox was globally eradicated in 1980, following a massive vaccination campaign led by the World Health Organization (WHO). India played a significant role in this global effort and was declared smallpox-free in 1977. This is a landmark achievement in public health. Therefore, among the given options, only Smallpox has been eradicated in India.
