Match List I with List II and select the correct answer: List-I (Process): (P) Cold Rolling, (Q) Hardness, (R) Impact loads, (S) Wire drawing. List-II (Property): (1) Indentation, (2) Ductility, (3) Malleability, (4) Resilience.
- A. P-4, Q-2, R-3, S-1
- B. P-3, Q-1, R-4, S-2
- C. P-1, Q-3, R-4, S-2
- D. P-3, Q-1, R-2, S-4
Answer: B. P-3, Q-1, R-4, S-2
Explanation: Cold Rolling leverages malleability (P-3) to compress metals into sheets. Hardness represents resistance to indentation (Q-1). Impact loads are absorbed through the material's resilience (R-4). Wire drawing relies on the material's ductility to be stretched into wires (S-2).
