Answer:

Correct option - (a) Leishmania female

Leptomonad stage is found in Leishmania females.

Explanation:

Leptomonads are a group of organisms under the genus Leptomonas. They are one of the most primitive groups of organisms under Trypanosomatidae (trypanosomatids).

Leptomonas has different types of stages having different morphological forms than other Trypanosomatids. They are flagellated organisms with their free flagella attached only to the undulating membrane. Gradually, they lose their free flagella and become a small round cells. This is their infective stage. During this stage, they are covered by a cyst.

The cystic cell is engulfed by the sand fly, Leishmania female. The cyst then breaks down to release the parasite. Thus, Leishmania female harbors the parasite in their gut.

So, the correct answer is Leptomonad stage is found in Leishmania females.
