Option 1 -> Incorrect matching: (B) should not match with (II), and (C) should not match with (III).
Option 2 -> (A)-(I): GDPMP is C+I+G+(X-M), (B)-(III): GDPFC = GDPMP - Net Product Taxes, (C)-(II): NDPMP = GDPMP - Depreciation, (D)-(IV): NDPFC = NDPMP - Net Product Taxes - Net Production Taxes.
Option 3 -> Incorrect matching: (B), (C), and (D) are incorrectly paired.
Option 4 -> Incorrect matching: (A) should match with (I), not (III).
Hence, Option 2: (A) - (I), (B) - (III), (C) - (II), (D) - (IV) -> The correct matching is: (A) GDPMP = C + I + G + (X - M) represents the expenditure approach to GDP. (B) GDPFC is obtained by subtracting net product taxes from GDPMP to convert from market prices to factor cost. (C) NDPMP is calculated by subtracting depreciation from GDPMP to get net domestic product. (D) NDPFC is derived by removing all indirect taxes (both net product taxes and net production taxes) from NDPMP to get the factor cost version of net domestic product. -> correct
