Answer 1

Answer: (B)

Smell

• Mosquitoes seek the blood of humans as food hence they are stimulated by various factors especially smell.
• Initially, they're attracted by the carbon dioxide we exhale. Body heat is probably important too, but once the mosquito gets closer, she will respond to the smell of a potential blood source's skin.
  
• Hence Mosquito traces the human body by smell.
