Correct answer: (A) P coping; R lime terracing; S rainwater pipe; (B) Q drip course; S rainwater pipe; T roof slab
Explanation
P caps and protects the parapet as coping; Q is the drip feature that interrupts surface water flow. R is the sloped terrace build-up, S the rainwater outlet/pipe and T the structural roof slab. Thus A and B are correct. Neither P nor R is the vent/rainwater component claimed in C, D.
