Correct answer: (d) Inequality of Income
Explanation
- A
Illiteracy
(a) Illiteracy. Literacy is counted from census and education surveys, not from a Lorenz curve.
- B
Unemployment
(b) Unemployment. Unemployment uses NSSO/PLFS rates, not Lorenz geometry.
- C
Population growth rate
(c) Population growth rate. Growth rates come from vital statistics and census, not Lorenz.
- D
Inequality of Income
(d) Inequality of Income. The Lorenz curve plots cumulative income share against cumulative population share; the Gini coefficient summarises the gap from equality. That stored measure is the official key.
Summary. Official key is (d) Inequality of Income. Lorenz is an income- (or wealth-) inequality graph. Illiteracy, unemployment and population growth use other tools. Neighbouring names are Gini, perfect-equality diagonal and Kuznets. Honour Lorenz for inequality.
