Answer 1

The correct option is A They are vectors of many disease

Vector-borne diseases are illnesses caused by an infectious microbe that is transmitted to vertebrates by another animal, usually an arthropod. This second animal is called a vector for the disease. There are a large number of viral, bacterial and parasitic diseases that can be transmitted by insect vectors. The most common vectors are blood-sucking insects such as mosquitoes, fleas, lice, biting flies, bugs, lice, helminths, and ticks. Most common vector-borne diseases affecting people and their vectors are malaria -anopheles mosquitoes, dengue, and chikungunya - Aedes mosquitoes.

So, the correct answer is option A.
