Diseases like malaria and dengue are spread by the bite of infected mosquitoes.
- Malaria is caused by the Plasmodium parasite, transmitted through the bite of an infected Anopheles mosquito.
- Dengue is caused by the dengue virus, transmitted by the bite of an infected Aedes mosquito.
Neither sneezing, coughing, nor direct contact are the primary methods of transmission for these diseases.
So, the correct answer is Option D: Mosquito bites.

Answer:
Diseases like malaria and dengue are spread by:
- Mosquito bites: The primary mode of transmission for both malaria and dengue is through the bite of infected mosquitoes. Female Anopheles mosquitoes transmit malaria, while Aedes mosquitoes transmit dengue.
- Sneezing: Malaria and dengue are not spread through sneezing. These diseases are not airborne and require the specific vector (mosquito) for transmission.
- Coughing: Similarly, coughing does not transmit malaria or dengue. The diseases are not respiratory infections and do not spread through respiratory droplets.
- Direct contact: Direct contact with an infected person does not result in the transmission of malaria or dengue. These diseases require the presence of the specific mosquito vector for transmission.
In conclusion, diseases like malaria and dengue are primarily spread through mosquito bites, not through sneezing, coughing, or direct contact. It is important to take preventive measures such as using mosquito nets, wearing protective clothing, and using mosquito repellents to reduce the risk of mosquito-borne diseases.

Bite of an infected mosquito can cause diseases like malaria and dengue.
(If the mosquito is infected and if the infected mosquito bites us so, it can cause malaria or dengue.)
