Answer 2

Answer:

Option (c) is the correct option. The number of heartbeats will be equal to the number of the pulse.

Explanation:

• Increases in the blood pressure in the arteries are caused by contractions of the heart that leads to a noticeable pulse when a person measures the heartbeat with the help of a stethoscope and pulse by placing the index finger on the left wrist for a minute.
• Pulse directly reflects the heart rate as pulse rate is defined as the number of heartbeats per minute. The speed at which the normal heartbeat is termed as the heart rate is between 60 to 100 beats per minute for an average adult while resting.
