Solution
The correct option is B J Haldane
In 1906, Haldane and Priestley discovered that respiratory reflex i.e. breath is caused by an excess of carbon dioxide in the blood and not by a lack of oxygen. They described the regulation of respiratory drive by carbon dioxide and its effects on blood hydrogen ion concentration The high ability of deoxygenated haemoglobin to bind with carbon dioxide was named as Haldane effect. Thus the correct answer is option B.
