Study carefully the following stages of life cycle of malarial parasite i.e., Plasmodium. Arrange these stages in the correct sequence and select the correct answer. 1.

The parasite reproduces asexually in liver cells, ultimately causing the rupturing of cells. 5. Two types of gametocytes i.e., microgametocytes and macrogametocytes develop in the RBCs. 6. Female Anopheleles mosquito takes up the gametocytes with blood meal of an infected person. 7. Mature infective stage of the parasite i.e., sporozoites escape from intestine and migrate to the mosquito's salivary glands. 8.
