What's the color of blood?
Correct Answer
C. Red
Explanation
Blood is red in color due to the presence of a protein called hemoglobin, which contains iron. When hemoglobin binds with oxygen, it turns bright red, giving blood its characteristic color. However, blood can appear darker or even blackish when it is deoxygenated, such as when it is returning to the heart from the body's tissues.

However, blood is always red, whether oxygenated or deoxygenated.
