• D. Hemocyanin

Answer 1

The correct option is A Haemoglobin

Haemoglobin (Hb) is a protein found in the red blood cells that carries oxygen in our body and gives blood its red colour. Haemoglobin levels vary from person to person. Men usually have higher levels of haemoglobin than women.
The normal range for haemoglobin for men is 13.5–17.5 grams per deciliter and for women is 12.0–15.5 grams per deciliter.
