Answer 1

An insect bites such as bites of bees or mosquitoes are harmless bites that result in stings and inflammation of the spot. Most of the bites cause mild itching or a mild allergic reaction. These resolve within days to weeks.

Step by step answer: An insect bites that result in inflammation if that spot is triggered by the alarm chemicals such as histamines and kinins. The release of histamines causes inflammatory reactions detected by the immune system that then produces antibodies that detect the allergen. Histamine increases the permeability of the capillaries to white blood cells and some proteins, to allow them to engage pathogens in the infected tissues. Kinins are present in the blood plasma that causes vasodilation and increases the permeability of the blood vessels. Most insect bites are the result of the host's allergy to injected chemicals. Bites and stings from animals such as spiders can result in morbidity and mortality, particularly in infants and adults. Insect bites can be prevented by taking appropriate measures such as wearing full sleeves and full-length clothes while traveling. Sleeping under mosquito nets can prevent mosquito bites at night. Using insect repellent creams and gels on the body and spraying insect repellent in the house.
Hence, the correct option is B. Histamines and kinins

Note: An insect bites can also become a medium to spread communicable diseases such as Yellow fever, chikungunya virus insects which are fatal. Insect bites also result in diseases associated by insects such as dengue, malaria, tick fever, leishmaniasis, lyme disease, etc.
