Verified step by step guidance

Begin by identifying the components of blood and their roles. Blood consists of red blood cells, white blood cells, platelets, and plasma.

Understand the role of red blood cells, which are primarily responsible for transporting oxygen from the lungs to the tissues and returning carbon dioxide from the tissues to the lungs.

Recognize the function of plasma, which carries nutrients, hormones, and waste products throughout the body.

Consider the role of blood in regulating body temperature. Blood vessels can expand or contract to help dissipate or retain heat, but blood itself does not produce heat.

Evaluate the options given in the problem. The primary function of blood is to transport oxygen and nutrients to cells, which aligns with the roles of red blood cells and plasma.
