Answer 2

#Red official

Due to presence of haemoglobin pigment, our red blood cells are red in colour.

Haemoglobin (Hb) is a protein found in the red blood cells that carries oxygen in your body and gives blood its red colour. Haemoglobin levels vary from person to person. Men usually have higher levels than women. A haemoglobin “cut-off” level is set for blood donation to ensure that your haemoglobin will not drop below normal after you have donated blood.
