A)32/min
B)42/min
C)52/min
D)72/min

Answer 1

The number of times a person’s heart beats per minute is known as the heart rate. It is also known as the pulse. The heart rate is different from one person to another person. The rate of the heartbeat depends on the individual's age, body size, heart conditions and also depends on whether the person is sitting or moving or using any type of medication and even the air and temperature.

Complete answer:
-In the center of the chest heart is a muscular organ. The heart pumps the blood containing Oxygen and nutrients throughout the body and brings back the waste product and this all carries out when the heartbeats.
-So, the number of times the heartbeats in the space of a minute is known as the heart rate. The right amount of blood at the right rate is supplied by a healthy heart for whatever the body is doing at that time.
-When the person is not active the normal heart rate is between 60 to 100 beats per minute and this is known as the resting heart rate. If a person is active then he needs to wait at least 5 minutes before measuring the heart rate because at that time the heart beats faster to get more oxygen in the working muscles.
-The faster the heart will beat when harder the body is working.
Example - When a person is sprinting, the heart rate is much faster than the heart rate when the person is walking. It's normal for the heart to beat 160 beats per minute or more when a person is exercising.
-Cafe, nicotine, recreational drugs, and some kind of medications are the other things that can make the heart beat faster.
-Also when the person feels strong emotions like anxiety or fear that time also the heart beats faster. The resting heart beats for the athletes is less than 60 bpm.

So, the correct answer is, "72/min".

Note:
-When hard does not beat in a regular and steady rhythm then it is known as the irregular heart rate on an arrhythmia.
-With the normal range the resting heart rate can vary among persons and can increase in a response to a difference of changes like exercise, the temperature of the body, emotional triggers, and position of the body. I like standing, walking, or sitting.
