Neurons generate and conduct electrical impulses. So this one is correct.
Epithelial cells line the cavities and surfaces of blood vessels and organs, protect underlying tissue, regulate the exchange of chemicals, and secrete various substances. They do not react to stimuli, however neurons do.
Smooth muscles helps the skeleton move, smooth muscle is found in blood vessels and some organs, and cardiac muscle helps the heart beat and pump blood. They are however, not components of blood.
