Mark the incorrect statement in context to oxygen binding to Hb

1.  higher pH

2.  lower temperature

3.  lower pCO2

4.  higher pO2

 (d) There are various factors which affect the binding of oxygen with Hb. These factors are
(i) Low temperature
(ii) Low H plus concentration (low pH)
(ili) Low diphosphoglyceraldehy
So, higher p oxygen is the in correct statement.
