Gray Water consists of:
(A) Kitchen waste water (B) Waste water containing fecal matter (C) Wastewater from industrial units (D) Bathroom waste water (E) Water from agricultural run-off
Choose the correct answer from the options given below:

Correct option is D

Gray Water refers to relatively clean wastewater from sources like kitchen waste water (A) and bathroom waste water (D). This excludes water contaminated with fecal matter, industrial waste, and agricultural run-off, which are typically considered more polluted and hazardous.
Information Booster: 1. Gray Water: Reusable waste water from sinks, baths, and laundry, but not from toilets or industrial processes.
2. Black Water: Waste water containing fecal matter or sewage, which requires more treatment before reuse.
3. Reuse: Gray water can be repurposed for non-potable uses such as irrigation and flushing toilets.
