A Correct answer
Explanation

Hemoglobin is a protein in red blood cells that binds to oxygen in the lungs and transports it to tissues throughout the body. Each hemoglobin molecule can carry four oxygen molecules. The other options are incorrect - hemoglobin does not destroy bacteria (white blood cells do), prevent anemia (it causes anemia when deficient), or utilize energy directly.
