Suggested Answer: A Vote an answer

Comprehensive and Detailed Explanation From Exact Extract:
Pervious paving allows water to infiltrate through surfaces, reducing runoff and preventing erosion and surface water accumulation on site. It is an effective stormwater management technique suited to infill sites where space is limited.
A catchment area (B) collects water but does not prevent erosion or surface water by itself.
Horizontal overhangs (C) provide shading and weather protection but do not affect surface water runoff.
NCARB PPD guidelines emphasize permeable surfaces as key components of sustainable site design to manage stormwater onsite.
