Ai-b, ii-a, iii-d, iv-c

Bi-a, ii-c, iii-b, iv-d

Ci-d, ii-b, iii-c, iv-a

Di-b, ii-d, iii-a, iv-c ✓ Correct

Correct answer: (D) i-b, ii-d, iii-a, iv-c

Explanation

Ordinal scale fits satisfaction level, ratio fits salary, nominal fits colour of hair, and interval fits difference in Celsius temperature.

Colour of hair carries only labels with no order, so it is nominal, matching iii with a.

Salary has a true zero and allows ratios, so it is a ratio variable, matching ii with d.

Celsius temperature difference has equal intervals but an arbitrary zero, making it interval, matching iv with c.

Options that call hair colour ordinal or salary interval misjudge the presence of a true zero and of order.

Only the ratio scale permits meaningful statements such as one value being twice another.
