Secondary hypertension is diagnosed when the high blood pressure is caused by another medical issue or disease in the body. Option A is incorrect because while a sedentary lifestyle can contribute to hypertension, it is not the main cause of secondary hypertension. Similarly, genetic predisposition (option B) can play a role in primary hypertension, but not in secondary hypertension. Finally, excessive salt intake (option D) can lead to high blood pressure, but it is not the underlying cause of secondary hypertension.
