All of the above.
💡 Explanation:
A. The systolic blood pressure is the pressure that develops in arteries when the ventricles contract and the diastolic pressure develops when the ventricles relax. The normal range of blood pressure is 120/80 mm Hg. In hypertension, the blood pressure elevates to 130-140 mm Hg systolic and 90-100 mm Hg diastolic pressure.
B. Arteriosclerosis occurs due to deposition of plaque in the arteries. This can occur due to deposition of calcium, cholesterol etc. It is linked with hypertension and Diabetes Miletus.
C. Atherosclerosis results due to building up of fatty deposits in arteries due to which they become inelastic.
Hence, the correct answer is 'All of the above'.
