The correct answer is D. All of the above.
Kerala has a high life expectancy of 75.9 years, which is higher than the national average of 69.3 years. This is due to a number of factors, including access to healthcare, nutrition programs, and sanitation and hygiene.
Kerala has a well-developed public healthcare system that provides free or low-cost care to all citizens. This includes primary care, secondary care, and tertiary care. The state also has a number of government-run hospitals and clinics, as well as private hospitals and clinics.
Kerala also has a number of nutrition programs that provide food to pregnant women, lactating mothers, and children under the age of five. These programs help to ensure that these groups of people have access to the nutrients they need to stay healthy.
Kerala also has a good sanitation and hygiene system. The state has a high rate of access to toilets, and it has a number of programs to promote handwashing and other hygiene practices. This helps to prevent the spread of diseases, which can lead to premature death.
All of these factors contribute to Kerala’s high life expectancy.
