The Correct Option is A

Solution and Explanation

The correct answer is B: Liver cells & R.B.C.
Through the bloodstream, the sporozoites reach the liver sinusoids and there they leave the blood circulation to invade a hepatocyte, after multiple transmigration events. In the hepatocyte, they undergo one asexual replication cycle that results in a liver schizont containing thousands of merozoites (yellow).

Asexual Reproduction

The mode of reproduction in which a new offspring is produced by a single parent is known as asexual reproduction. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.

Features of Asexual Reproduction:

  1. Only single parents are involved.
  2. The fertilization or gamete formation cannot take place.
  3. This process of reproduction occurs in a very short time.
  4. The organisms multiply and grow rapidly.
  5. In this offspring produced is genetically similar.
