Answer:
D
Explanation:
Flood water during a storm surge carry sediments, debris and other pollutants to water bodies when the waters are finally subsided
Effluents from factories that flow to the water bodies, if left untreated will cause water pollution
Tillage in farms leaves the topsoil loose and exposed to surface runoffs. Soil, including the applied pesticide and chemical fertilizers on the farm, are swept away by the runoffs ultimately ending up in water sources.
