Solution

The correct option is A
True

We can feel the heart beat on our wrists because arteries expand and contract as blood flows in it. As the heart expands and contracts, the blood is at different pressures during expansion and contraction. This causes a change in size of the arteries which we can feel when the arteries are close to the skin (such as near the wrist and temple).
