If the oxygen-haemoglobin dissociation curve is shifted to the right, it means that haemoglobin is less saturated at a given partial pressure of oxygen. This occurs when there is an increase in factors that cause haemoglobin to release oxygen more readily, such as a decrease in pH (also known as acidosis) or an increase in partial pressure of carbon dioxide. Therefore, choice B is the best option as it describes a decrease in pH, which causes a right shift in the curve.
