Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R. Assertion A: During the transportation of gases, about $20-25$ percent of $\mathrm{CO}_2$ is carried by Haemoglobin as carbamino-haemoglobin. Reason R: This binding is related to high $\mathrm{pCO}_2$ and low $\mathrm{pO}_2$ in tissues. In the light of the above statements, choose the correct answer from the options given below.
Match List I with List II :  Choose the correct answer from the options given below :
