Verified by Experts

The correct Answer is:
C
Sickle-cell anaemia is an autosomal recessive gene disorder in which sickle-celled RBCs are formed instead of normal ones. They carry very less content of `O_(2)` as their haemoglobin is malformed. The person suffering from this disease show symptoms of anaemia.
