Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion (A): During the transporation of gases, about 20-25 percent of CO2 is carried by haemoglobin as carbamino-haemoglobin.
Reason (R): This binding is related to high pCO2 and low pO2 in the tissues

In the light of the above statements, choose the correct answer from the options given below.
1.  (A) is True but (R) is False.
2.  (A) is False but (R) is True.
3.  Both (A)and (R) are True and (R) is the correct explanation of (A).
4.  Both (A) and (R) are True but (R) is not the correct explanation of (A).
