Answer: Option B
Explanation: Mosquitoes cause more human suffering than any other organism. Mosquito acts as a vector for the bacteria and viruses, responsible for the diseases such as malaria, dengue, encephalitis and yellow fever etc. When mosquito bites a human it causes severe skin irritation through an allergic reaction to the mosquito's saliva, this is what causes the red bump and itching.
