Option 4: (A) - (II), (B) - (i), (C) - (IV), (D) - (III) -> Let's match each correctly:

(A) GDP at constant price matches with (ii) - GDP at constant price is Real GDP, which uses base year prices to measure output. It increases only when there is an actual increase in the quantum (volume) of output, as price changes are eliminated.

(B) GDP at current price matches with (i) - GDP at current price uses current market prices and is known as Nominal GDP. It reflects both changes in output and price levels.

(C) Welfare of the people matches with (IV) - Welfare is measured in terms of the availability of goods and services. Greater availability and access to diverse goods and services indicates higher welfare levels.

(D) Factor income matches with (III) - Factor income refers to income earned by factors of production (land, labor, capital, and entrepreneurship) and is known as earned income, as opposed to transfer payments.
