Consider the following statements and choose the correct option: Statement (A): An increase in hydrogen ion concentration (lowered pH) decreases hemoglobin's affinity for oxygen, thereby favoring the dissociation of oxyhemoglobin. Statement (B): At lower O2 tension, oxyhemoglobin dissociates more readily in the presence of salts compared to their absence due to ionic interactions affecting the conformation.
