Correct Answer: Connective tissue

Solution : The correct option is Connective tissue.

In the human body, blood is classed as connective tissue. It is made up of numerous biological components floating in a liquid matrix called plasma, including red blood cells (erythrocytes), white blood cells (leukocytes), and platelets. The purpose of connective tissues is to connect, support, and protect other tissues and organs in the body, and blood falls into this category due to its involvement in transportation, immunological defence, and clotting.
