Answer 1

The correct option is A

Female Anopheles mosquito

The correct option is A.

Explanation of correct option:

1. Malaria is an infectious illness spread by mosquitos that are caused by Plasmodium protozoan.
2. It is passed from an infected person to a healthy person by a female Anopheles mosquito carrier.
3. Because the Plasmodium parasite is prevalent in the blood of infected humans, it is easily transmitted to mosquitos.
4. Plasmodium remains in the mosquito for a few days before being transmitted to the next human via the saliva during the mosquito bite.
5. Malaria symptoms include fever, chills, muscle pains, nausea, vomiting, and headache.

Explanation of incorrect options:

Option B:

1. Cockroaches can transmit a variety of illnesses.
2. However, unlike mosquitos, they are not direct disease carriers.
3. Transmission happens indirectly, rather than directly, through eating or contact with cockroach-contaminated objects.

Option C:

1. The housefly is a key contributor to infectious illnesses.
2. It is the most frequent type of fly seen in our homes.
3. Housefly feeds on waste materials and edibles.
4. When it flies from trash to food, it transmits harmful bacterial organisms from waste.
5. Because of the ingestion of such foods, the individual becomes infected with microorganisms and becomes ill.

Option D:

Butterfly has no effect on people and there is no probability that they may evolve to infect humans.

Final answer: Carrier of malaria-causing protozoan is female Anopheles mosquito.
