Q: Which component is not transported by blood among the following options?  

Answer: C

Blood transports various components throughout the body, including hormones, oxygen, carbon dioxide, nutrients, and waste products. However, heat is not transported by blood. Heat is mainly transferred through conduction, convection, and radiation. Blood plays a crucial role in maintaining the body's homeostasis and provides the necessary nutrients and oxygen to various organs and tissues. Lymph, on the other hand, is not transported by blood. It has its own set of vessels, and it helps in removing excess fluid and waste products from the tissues.
