Explanation:

The "Anaemia Mukt Bharat" strategy is a comprehensive strategy to reduce the prevalence of anaemia in India. The main components of the strategy include:

Prophylactic Iron and Folic Acid supplementation: This is provided to specific vulnerable groups, including pre-school children, adolescents, and pregnant women. There's no mention of prophylactic calcium supplementation for these groups in the context of the Anaemia Mukt Bharat strategy. So, the first statement is not accurate.

Delayed cord clamping: This is promoted as a part of essential newborn care practices to ensure that the baby receives most of the iron-rich blood from the placenta which can help prevent anaemia in infancy.

Deworming: Periodic deworming is provided to children and adolescents to reduce the worm load, which can lead to anaemia.

Addressing non-nutritional causes of anaemia: This includes interventions to tackle diseases like malaria, hemoglobinopathies, and fluorosis which can contribute to anaemia, especially in endemic areas.

So, three out of the four given statements are correct
