Explanation:

The correct answer is Price levels vary from State to State.

• Poverty lines would vary from State to State because of inter-state price differentials.
• According to the Planning Commission, in 2011-12 for rural areas, the national poverty line by using the Tendulkar methodology is estimated at Rs 816 per capita per month in villages and Rs 1,000 per capita per month in cities.
• The poverty line depends on the income profile of the population and on the basis of consumer expenditure.
• The poverty line is a function of the cost of consumption basket which varies from state to state.
