Solution

The correct option is D Both A and C
  1. Dogs use their sense of smell, to find and follow a track. Dogs have a highly sensitive olfactory system superior to humans.
  2. 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 Dog and Mosquitoes have a strong sense of smell.
  • So, the correct answer is 'Both A and C'.
