Option 1 -> Incorrect matching: GDP is about domestic territory (III), not residents abroad (I).
Option 2 -> Incorrect: NDP relates to domestic territory income (IV), not all production in country (III).
Option 3 -> Incorrect: NDP should match with domestic territory income (IV), not factor income belonging to country (II).
Option 4 -> Correct matching of all economic concepts with their definitions.
Hence, Option 4: (A) - (III), (B) - (IV), (C) - (I), (D) - (II) -> GDP measures all production within domestic territory regardless of ownership (III). NDP represents income earned by factors within domestic territory (IV). GNP captures output by nation's residents wherever they are located (I). National Income is the sum of factor incomes belonging to the country (II). The key distinction is 'Domestic' (territory-based) vs 'National' (residency-based) in these economic measures. -> correct
