The Rangarajan Committee's methodology for determining the poverty line includes three components: (1) a food component based on average requirements of calories, fat, and protein, (2) a normative level of expenditure for essential non-food items such as clothing, housing, mobility, and education, and (3) a behaviorally determined expenditure for other non-food items. Therefore, all three components listed in the question are included in the Rangarajan Committee's methodology.
