The carrier for amoebiasis is:A Entamoebia histolytica B Mosquito C Musca D Plasmodium vivax

Step 1: Break Down the Problem

The question asks to identify the carrier responsible for amoebiasis among the given options.

Step 2: Relevant Concepts

Amoebiasis is primarily caused by the parasite Entamoeba histolytica. Understanding the transmission and the role of carriers in spreading diseases will help identify the correct option.

Step 3: Analysis and Detail

1. Entamoeba histolytica: This is the causative agent of amoebiasis and can be found in contaminated water or food. It is directly responsible for the disease, hence it is not a carrier but the causative organism.

2. Mosquito: Generally a carrier for diseases such as malaria and dengue, not amoebiasis.

3. Musca (house fly): While flies can mechanically transfer the cysts of Entamoeba histolytica from feces to food, they are not the definitive carrier.

4. Plasmodium vivax: This is a malaria-causing parasite and not connected to amoebiasis.

Step 4: Verify and Summarize

The clear association of Entamoeba histolytica with amoebiasis indicates that it is the organism responsible for the disease, not a carrier. However, house flies can play a role in the transmission.

Final Answer

The most appropriate answer relating to the carrier context is C: Musca, as house flies can contribute to the spreading of the organism.
