Question

Match the aspects in Group I with the corresponding items in Group II. 

• A. P-4, Q-5, R-2, S-3
• B. P-5, Q-1, R-4, S-2
• C. P-2, Q-4, R-5, S-1
• D. P-2, Q-5, R-4, S-3

Hint:

Safety, efficiency, and accessibility standards often correspond to very specific engineering devices—matching requires understanding each device's function.

Answer 1

The Correct Option is D

Fire safety (P) corresponds to a zero–strength barrier (2), which provides controlled fire isolation and prevents fire spread.
Seismic safety (Q) corresponds to an auxiliary damper (5), which reduces vibrations and dissipates seismic energy in structures.
Water efficiency (R) is associated with an aerator (4), a device installed on taps to conserve water by mixing air with the water flow.
Accessible design (S) corresponds to a stair lift (3), which aids individuals with mobility limitations.
Thus, the correct matching is: \[ P-2,\; Q-5,\; R-4,\; S-3. \] Final Answer: (D) P-2, Q-5, R-4, S-3
