The doctor further explained that “Blood forms a clot to begin the process of healing. Some components block the leakage of blood and close the body from the outside world. This is the clot and the process of rebuilding the skin starts as soon as it is formed.”

Solution

The correct option is A
Platelets

The doctor is referring to a type of blood cells called platelets. Platelets are smallest blood cells and perform a very important function in the process of blood clotting. They form a fine meshwork at the site of wound. In this mesh, RBCs get trapped and such a clot prevent oozing of more blood from the site of wound.
