Assertion: `Hb^(S) Hb^(S)` is homozygous condition of sickle cell anaemia.
Reason: It occurs due to substitution of glutamic acid by valine at sixth position in `beta`-chain of haemoglobin.

A

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false
