The correct answer is (a) Bihar.
Bihar is a state in eastern India. It is the third-largest state in India by population, after Uttar Pradesh and Maharashtra. Bihar is also one of the poorest states in India, with a per capita income of less than half the national average.
Malnutrition is a major problem in Bihar. According to the National Family Health Survey (NFHS-4), 46.3% of children under the age of five in Bihar are stunted, meaning they are too short for their age. This is the highest rate of stunting in India.
There are a number of factors that contribute to malnutrition in Bihar. One factor is poverty. Many families in Bihar cannot afford to provide their children with a nutritious diet. Another factor is lack of access to healthcare. Many people in Bihar live in rural areas where there are few hospitals or clinics. As a result, they may not have access to the medical care they need to prevent or treat malnutrition.
The government of Bihar has taken some steps to address the problem of malnutrition. For example, the government has launched a number of programs to provide food supplements to children and pregnant women. However, more needs to be done to address this serious problem.
The other options are incorrect because they are not states in India.
