Match the columns:

Column-$I$	Column-$II$
$(a)$ Pre-erythrocytic cycle	$(1)$ Meta-cryptomerozoites enter $RBC$ and become spherical in shape.
$(b)$ Exo-erythrocytic cycle	$(2)$ Sporozoites in saliva are introduced into human blood.
$(c)$ Endo-erythrocytic cycle	$(3)$ Breaks the liver cells and comes out into the blood.

(A) The correct matching is as follows:
$(a)$ Pre-erythrocytic cycle: In this stage, sporozoites from the mosquito's saliva enter the human blood and reach the liver cells.
$(b)$ Exo-erythrocytic cycle: In this stage, the parasite multiplies within the liver cells, eventually breaking them and releasing merozoites into the blood.
$(c)$ Endo-erythrocytic cycle (Erythrocytic cycle): In this stage, the merozoites (or meta-cryptomerozoites) enter the $RBC$s, where they become spherical and undergo further development.
Therefore, the correct sequence is $(a-2), (b-3), (c-1)$.
