The correct answer is A. Reducing fevers.
To find the answer, we should look for information about the uses and benefits of quinine. Quinine is a natural compound that is extracted from the bark of the cinchona tree. It has been used for centuries as a treatment for malaria, which is caused by a parasite transmitted through mosquito bites.
Although quinine is primarily known for its antimalarial properties, it is also effective in reducing fevers. When used in appropriate doses, quinine can help lower body temperature and alleviate fever symptoms. It does so by interfering with the parasites' ability to multiply and infect red blood cells, ultimately reducing fever associated with malaria and related diseases.
Therefore, the correct answer is A. Reducing fevers.
