Final answer:
Hypertension, cigarette smoking, and lack of exercise are all predisposing factors of heart disease.
Step-by-step explanation:
All of the above - hypertension, cigarette smoking, and lack of exercise - are predisposing factors of heart disease. Hypertension, or high blood pressure, puts strain on the heart and blood vessels, increasing the risk of heart disease.
Cigarette smoking damages blood vessels and reduces oxygen supply to the heart, while lack of exercise and sedentary lifestyle contribute to obesity and high cholesterol levels, which are also risk factors for heart disease.
