Under 33 CFR §151.05, 'graywater' is defined as drainage from specific sources. Which of the following drainage sources is expressly EXCLUDED from the definition of graywater?

Why D is correct

33 CFR §151.05 defines graywater as drainage from dishwater, shower, laundry, bath, and washbasin drains, but expressly states it does not include drainage from toilets, urinals, hospitals, animal spaces, and cargo spaces. Hospital drains are therefore excluded.
