Solution

The correct option is A Both assertion and reason are correct and reason is the correct explanation for assertion.
Insects have blood that does not contain any pigment protein like hemoglobin. The blood is not involved in the transport of oxygen. The oxygen is distributed with the help of a system that is comprised of tubes and air sacs. The blood does not have hemoglobin and is colorless, pale yellow, or green. The blood is known as hemolymph which does not perform the function of transport of oxygen. In human beings, blood is used to carry oxygen from the lungs to the tissues.
Thus, the correct answer is option A.
