Answer:

Answer is part (A) Trophozoite

Answer 2

Answer:

a) Trophozoite

Explanation:

Entamoeba histolytica is an anaerobic parasitic amoebozoan, part of the genus Entamoeba.[1] Predominantly infecting humans and other primates causing amoebiasis, E. histolytica is estimated to infect about 35-50 million people worldwide.[1] E. histolytica infection is estimated to kill more than 55,000 people each year.[2] Previously, it was thought that 10% of the world population was infected, but these figures predate the recognition that at least 90% of these infections were due to a second species, E. dispar.[3] Mammals such as dogs and cats can become infected transiently, but are not thought to contribute significantly to transmission.

Entamoeba histolytica has two morphological forms: the infectious cyst and the invasive trophozoite, both of which may be found in the feces of infected patients (cysts are typically found in formed stool, whereas trophozoites are typically found in diarrheal stool)
