The measurement of poverty-line in India is based on the criteria of

The correct choice is: “Calorie consumption”

India’s official poverty line has traditionally been anchored to a minimum calorie requirement: the monthly consumption expenditure needed to obtain about 2,400 kcal per person per day in rural areas and 2,100 kcal in urban areas (the norm used since the 1979 Alagh Task Force). Later methods (Tendulkar, Rangarajan) widened the consumption basket but still built on nutritional norms.

Employment, housing and education are indicators of deprivation, but they are not the basis of the poverty line.
