Answer & Solution

Correct Answer

(D) (А)-(III), (В)-(IV), (C)-(I), (D)-(II)

Step-by-step Solution

Detailed explanation

(A) Overall order \( = 0.2 + 0.3 + 1 = 1.5 = \frac{3}{2} \). (A)-(III) (B) Overall order \( = 0.2 + (-0.3) + 1 = 0.9 = \frac{9}{10} \). (B)-(IV) (C) Overall order \( = 1 + 0.8 + (-1) = 0.8 \). (C)-(I) (Approximate Match assuming typo in question as \(0.8 \ne 0.3\)) (D) Overall…
