Complete answer:
Entamoeba histolytica can be referred to as an anaerobic parasitic amoebozoa which is a part of the genus Entamoeba. This pathogenic amoeba belongs to the phylum Protozoa, the class Sarcodina and the order Lobosa. It mainly causes intestinal and extraintestinal infections in human beings. It acts as a parasite in humans. The infection of the E. histolytica in humans and other primates is known as amoebiasis. Amoebiasis is also known as amoebic dysentery. It is caused due to the attack of the protozoan parasite in the human large intestine. Generally, they survive in the large intestines and produce eggs or cysts and move out of the body with the stool which may lead to diarrhoea and colitis. The infection of E. histolytica may have mild to severe symptoms. It shows symptoms such as fever, chills, nausea, weight loss, abdominal discomfort, diarrhoea that may include blood or mucus with periods of constipation. Amebiasis may be caused due to living in areas with poor sanitary conditions. In also can be caused by swallowing cysts of the parasite or oral-anal sexual contact with an infected person. Ingesting water or food which is contaminated by faeces of infected people is one of the major ways of this infection. So, the amoeba enters our body with infected food and water. Therefore, we must wash vegetables before their consumption. And sometimes the Entamoeba histolytica can be present in our hand also. When we take food, it can enter our body mixing with the food. Therefore, we must wash our hands properly always before taking a meal.
Thus, the right option is D.
