Question

Accepted Answer

The correct option is (2):
Both statements are incorrect. This option is the correct choice because both statements contain significant factual or definitional inaccuracies. Statement (i) claims that the injection of Erythropoietin (EPO) is a type of blood doping. By a strict definition, 'blood doping' refers to the manipulation of blood components, typically through the transfusion of blood or red blood cells. EPO abuse, on the other hand, involves injecting a drug (a peptide hormone) that *stimulates* the body's natural production of red blood cells, which is a method of pharmacological doping, making the statement technically incorrect. Statement (ii) is factually incorrect because the hormone Erythropoietin (EPO) is predominantly produced by the **kidneys** in adults, not the liver. Since the liver is not the primary production site, this statement is wrong. As both statements are incorrect, the composite option stating "Both the statements are incorrect" is the most accurate.

The incorrect option is (1):
Both the statements are correct. This option is incorrect because Statement (ii) is factually wrong according to basic human physiology. The vast majority of the hormone Erythropoietin is produced and secreted by the kidneys, which function as the primary oxygen sensor for the body to regulate red blood cell count. Attributing the production of this renal hormone to the liver is a major error. Furthermore, Statement (i) is technically inaccurate as EPO is classified as a peptide hormone and growth factor abuse (S2) rather than direct blood manipulation (M1), which is the strict definition of blood doping.

The incorrect option is (3):
Only statement (i) is correct. This option is incorrect because Statement (ii) is definitively false, as the kidneys are the main organ responsible for the production of Erythropoietin. A correct option would need to reflect the inaccuracy of Statement (ii). While EPO abuse is commonly referred to as blood doping, its technical classification as a growth factor/hormone and its mechanism of action (stimulation vs. transfusion) allow for it to be considered definitionally incorrect in a precise context.

The incorrect option is (4):
Only statement (ii) is correct. This option is incorrect because Statement (ii) contains a factual error regarding the site of hormone production. The liver produces only a minor amount of Erythropoietin; the kidneys are the primary site. Since a core piece of medical information within the statement is wrong, the statement itself is incorrect. Therefore, the option that relies on Statement (ii) being correct cannot be chosen.
