Which of the following is a measure for the control of bilharzia?

The measure for the control of bilharzia is the application of molluscicides in water bodies. Molluscicides are chemicals that are used to kill snails, which are intermediate hosts for the parasites that cause bilharzia. Cutting low bushes around homes may reduce the risk of exposure to ticks that transmit other diseases, but it is not an effective measure for the control of bilharzia. Screening windows and doors with mosquito nets is a measure for the prevention of malaria, which is caused by a different parasite that is transmitted by mosquitoes. Application of herbicides in water bodies is not a recommended measure for the control of bilharzia as it can have negative impacts on the aquatic ecosystem.
