Listed below are four respiratory capacities (1-4) and four jumbled respiratory volumes of a normal human adult. 

Respiratory capacities Respiratory volume
(a) Residual volume 2500 mL
(b) Vital capacity 3500 mL
(c) Inspiratory reserve volume 1200 mL
(d) Inspiratory capacity 4500 mL

1. (a) 2500 mL, (d) 4500 mL

2. (c) 1200 mL, (a) 2500 mL

3. (b) 4500 mL, (c) 2500 mL

4. (d) 4500 mL, (b) 3500 mL

Which one of the following statements is incorrect?

1. The residual air in the lungs slightly decreases the efficiency of respiration in mammals
2. The presence of non-respiratory air sacs increases the efficiency of respiration in birds
3. In mammals, circulating body fluids serve to distribute oxygen to tissues
4. The principle of countercurrent flow facilitates efficient respiration in the gills of fishes
