Answer:
c) The blood not the place to fight Malaria
Explanation:
This wording is weird but I think it is C. Anti-malarial drugs are not for curing the disease because they only kill the parasites in the blood. Malaria develops in the blood stage and the liver. The anti-malarial drug kills the blood-stages of the parasite but not the liver ones. The liver ones can reinfect the blood and cause malaria again.
