Answer 1

Hint: Amoebic dysentery is a parasitic infection of the colon that is caused by the species of Amoeba.
It is also called amoebiasis. It is most common in those areas where people use untreated water.

Complete answer:
Amoebiasis may spread from one person to another through eating or drinking uncooked food and washing the fruits or vegetables with contaminated water. The common symptoms of Amoebiasis include fever, chills, diarrhea, abdominal pain, the passage of stool with blood and mucus. In severe cases, there will be inflammation of the intestine. The mode of transmission is mainly through the fecal-oral route where the water source is contaminated by the fecal matter. The incubation period is variable that may range from a few days to a month. Usually, it is 2- 4 weeks.
Entamoeba histolytica is an anaerobic parasite that belongs to the genus Entamoeba. It mainly infects humans and other pirates. It is responsible for the cause of amoebiasis or amoebic dysentery. Entamoeba gingivalis is an opportunistic Amoeba. It is present in the mouth inside the gingival pocket near the teeth base. It is present in those people who have a gum infection. The disease is transmitted from one person to another through sharing eating utensils.
Entamoeba coli- It is a non- pathogenic species of Entamoeba that is present in the gastrointestinal tract of humans as a commensal parasite. Humans are infected by this by the contaminated food and water. Amoeba proteus- It is a protozoan that moves by extending the pseudopodia. It usually occurs in freshwater. They do not infect humans.

So, the correct answer is option A.
