Solution
The correct option is A Ookinete
Gametocytes pass to female Anopheles mosquitoes while feeding on an infected human. Male and female gametocytes undergo gametogenesis within the midgut of the mosquito. The gametes then fertilize to form a zygote (diploid structure), which further develops into motile ookinetes (diploid). Ookinetes cross the midgut epithelium to form an oocyst. In the oocyst, thousands of sporozoites (haploid) form by meiosis, which upon bursting of the oocyst wall enter the salivary gland. From there, sporozoites are transmitted to the next human during the subsequent mosquito bite. Trophozoites and merozoites are also haploid stages that occur in human hosts.
