Statement (b) is correct as intrapulmonary pressure is lower than the atmospheric pressure during inspiration. Other statements can be corrected as (a) Inspiration occurs due to external intercoastal muscles. (c) Inspiration occurs when atmospheric pressure is more than intrapulmonary pressure. (d) Inspiration is initiated due to contraction of diaphragm.

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.
