Answer 1

Hint: Vector borne diseases are the ones that transmit from one person to another person by some vectors called mosquitoes, ticks, fleas, etc. And they transmit the parasites like viruses, bacteria, protozoans, etc.

Complete answer:
> Malaria: It is the disease transmitted by the female Anopheles mosquito, and the disease is caused by the bacteria called plasmodium, and 4 species are able to cause malaria.
Whenever a mosquito bites the infected person, bacteria enter the mosquito and where they replicate and stored in the salivary gland of the mosquito and when it bites another person, it transmits the disease. So this option is correct.

> Sleeping disease: It is also called as African trypanosomiasis which is caused by the parasite called Trypanosoma brucei, this disease is mainly occurring or transmitted by Tsetse flies bite, which is already infected by this parasite,
This disease is endemic in the areas of Africa, and it causes death if not treated properly, so this is the wrong Option.

> Kala-Azar: This is also called leishmaniasis caused by the protozoan parasite, Leishmania and it is spread by phlebotomine sand-fly.
It got the kala azar because in this light colored person turns to grey, kala azar means black or dark color, so this is the wrong option.

> Filariasis: This disease is caused by a parasite called Wuchereria Bancrofti, which is the roundworm belong to helminthiasis, and this disease is spread by
Bloodsucking insects and mosquitoes, it mainly affects the lymphatic system of humans, so it is the correct option.

Hence, the correct answer is both option (A) and (D).

Note: Most of the vector borne disease is controlled or prevented by protecting oneself from biting the mosquitoes, flys, and insects, and wearing clothes that cover the full body and using the repellants, etc.
