Correct Option (D)
The passage explicitly states that the methodology adopted in India to count the poor is debatable because it "exclusively relies on the notion of poverty as insufficient income or insufficient purchasing power." It further categorizes this as "income poverty" and argues that if poverty is about deprivations affecting human well-being, then income poverty is only one aspect. The core criticism is that the methodology is based on a narrow proposition of poverty defined solely by meagre income or buying capacity, neglecting broader aspects such as lack of opportunities and curtailed capabilities.
Incorrect Options:
Option (A): While there can be complexities in defining the poverty line, the passage's central argument for the methodology being debatable is not about confusion regarding the specific threshold of the poverty line. Instead, it critiques the fundamental assumption and definition of poverty (as income poverty) upon which the measurement is based.
Option (B): The passage does not identify the wide diversities in the condition of the rural and urban poor as the primary reason for the debatability of the methodology. While such diversities are relevant to the overall understanding of poverty, the passage's critique focuses on the narrow conceptualization of poverty itself (as income poverty) rather than the geographical variations in its manifestation.
Option (C): The passage does not discuss the existence or absence of a uniform global standard for measuring income poverty. Therefore, this point is not presented as a reason for the debatability of India's methodology within the provided text.
