upon deoxidation HbS can not produce tetramers and rather forms long polymers. So I think A and C are right! What is wrong with my thought?!!

Why can't it be D. The HbS are instable and that causes spontaneous sickling of the RBCs. Also low PaO2 can cause sickling in a person with Sickle cel trait.

HBS can polymerise upon low O2 tension or hypotonic stress. The polymerized HBS deforms RBC.

Where can we look this up? I think its either C or D.
Factors that induce sickling are:
-HbS in RbC>60%
-Reduced O2 tension
-High altitude
-Low O2 tension in the renal medulla
etc....
But what about the structure of the Hb?
