Solution
The correct option is A Haemoglobin
The colors and its variance are caused by a molecule in red blood cells called Hemoglobin, which contains the metal iron. Hemoglobin uses this iron to bind to oxygen molecules and transport the oxygen to all the cells in our body. WBC, plasma and secretion do not make the blood look red. Thus, option B is correct.
