Final Answer :
B
Explanation :
The spraying of breeding areas with DDT and other pesticides led to a sharp decrease in the spread of malaria in many areas. While the use of herbicides may affect the breeding areas, it is not a primary method of controlling malaria. There is currently no effective vaccine for malaria, and the solution of boiled water, salt, and sugar or rice is used to treat dehydration caused by malaria, but it does not directly contribute to decreasing the spread of the disease.
