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 CO$$_2$$ is carried by Haemoglobin as carbamino-haemoglobin.

Reason R: This binding is related to high pCO$$_2$$ and low pO$$_2$$ in tissues.

In the light of the above statements, choose the correct answer from the options given below.
