Answer: (C)

Verified step by step guidance

1. Begin by identifying the main components of the human circulatory system, which include the heart, blood vessels, and blood. These components work together to circulate blood throughout the body.
2. Understand the primary functions of the circulatory system. It is responsible for transporting oxygen, nutrients, hormones, and waste products to and from cells, thus playing a crucial role in maintaining homeostasis.
3. Recognize the interaction between the circulatory system and other organ systems. For example, it works closely with the respiratory system to exchange gases in the lungs and with the digestive system to absorb nutrients.
4. Clarify the role of the circulatory system in red blood cell production. While it transports red blood cells, their production occurs in the bone marrow, which is part of the skeletal system.
5. Evaluate the statements given in the problem. The statement 'The circulatory system is responsible for transporting oxygen and nutrients to cells' accurately describes one of the key functions of the circulatory system.
