d

Explanation:

Greywater use involves reusing water from sources like sinks, showers (excluding toilet water). To safely reuse greywater (e.g., for irrigation, toilet flushing), it needs a separate plumbing system to collect, transport, and distribute it, distinct from potable water plumbing. Water reclamation and desalination don't inherently require separate plumbing in the same way greywater use does (water reclamation is broader, desalination is for saltwater to freshwater, often integrated or with different infrastructure needs not focused on separate plumbing for reuse like greywater).

Answer:

C. greywater use
