D. Application of herbicides in water bodies
Correct Answer:
Option B – Application of molluscicides in water bodies
Explanation
Schistosomiasis, also known as bilharzia or ‘snail fever’, is a disease caused by parasites (worms called schistosomes) carried by freshwater snails.
Schistosomiasis control focuses on reducing disease through periodic, large-scale population treatment with medication;
a more comprehensive approach including potable water, adequate sanitation, and snail control would also reduce transmission.
