C Correct answer
Explanation

Liver is the first organ invaded by a malarial parasite. Malarial parasites enter human body as sporozoites and are carried to the liver where they mature into forms known as schizonts. Over the next one to two weeks, each schizont multiplies into thousands of other forms known as merozoites. The merozoites break out of the liver and re-enter the bloodstream.
