C

D
colloidal gold
Answer
colloidal antimony
Explanation
Solution
It is cured by colloidal antimony. It is the antimony compounds that are suspended in the colloidal solution. They target the Leishmania parasite that will cause cellular toxicity and thus inhibit the growth and replication of the parasite. But overtime, some of the species get resistant to the antimony containing compounds that will make them less effective. The toxicity of the compounds is one of the side effects of this method.
