Correct Option (A):
In India, the classification of persons below the poverty line has historically been based on defining a minimum standard of living. Initially, this standard was primarily linked to a minimum calorie intake, specifically 2,400 calories per person per day in rural areas and 2,100 calories per person per day in urban areas. This calorie norm directly translates to the requirement for a "minimum prescribed food basket" necessary to meet basic nutritional needs. While the methodology has evolved over time, shifting from purely calorie-based norms to a broader consumption expenditure approach (as recommended by committees like Tendulkar), the underlying principle of defining a minimum consumption standard, of which food is a fundamental component, remains central to poverty line estimation.
Incorrect Options:
Option (2): The criterion of getting work for a prescribed minimum number of days in a year relates to employment generation and social security schemes, such as the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA). It is not the direct basis for classifying individuals or households as being below the poverty line, although lack of employment can contribute to poverty.
Option (3): Belonging to specific social groups like agricultural labourer households or Scheduled Castes/Scheduled Tribes (SC/ST) indicates socio-economic vulnerability. While these groups often have a higher incidence of poverty, their social classification itself is not the defining criterion for determining whether they are below the poverty line. Poverty classification is based on economic indicators like income or consumption expenditure, not social identity.
Option (4): Daily wages falling below prescribed minimum wages is a measure related to labour laws and fair remuneration. While low wages can lead to poverty, the minimum wage threshold is distinct from the poverty line. The poverty line is designed to estimate the expenditure required to meet a basket of basic needs (food, shelter, clothing, etc.), whereas minimum wages are statutory rates for labour, which may or may not be sufficient to lift a household above the poverty line depending on other factors like employment duration and household size.
