A Correct answer
Explanation

Hemoglobin is a protein in red blood cells that binds oxygen in the lungs and transports it to body tissues. It gives blood its red color and is essential for aerobic respiration. Hemoglobin does not destroy bacteria (that's white blood cells), prevent anemia (it actually causes anemia when deficient), or directly utilize energy.
