Question

A. Hargovind Khurana
B. Christian Barnard
C. Watson
D. William Harvey

Answer 1

Hint: Heart transplant: It is an operation in which a diseased or failing heart is replaced with a healthier donor heart.
Heart transplant is a treatment usually done in those people whose condition hasn't improved enough with medications or other surgeries.
While a heart transplant is a major operation the chance of survival is good with appropriate follow-up care.

Complete answer:
Heart is an important organ which pumps blood throughout the body.
Heart supplies the nutrients and other essential minerals with the help of blood.
Heart weighs 300 g in males and 250 g in females.
Heart consists of four chambers:
1. Right Atrium
2. Left Atrium
3. Right Ventricle
4. Left Ventricle
Heart transplants occur because the heart is not working properly and even not working with other treatments.
Heart failure in adults can be caused by:
1. Cardiomyopathy
2. Coronary artery disease
3. Heart valve disease
4. A heart problem you're born with (congenital heart defect)
5. Ventricular arrhythmias
6. Failure of a previous heart transplant
In children, cardiomyopathy or congenital heart disease causes heart failure.
Another organ transplant may be performed at the same time as a heart transplant which is regarded as multiorgan transplant.
The first human heart transplant was performed on 3rd December in 1967 by a group of 30 doctors which was headed by Prof. Christian Barnard on Louis Washkansky who was 55 years old at that time at the Groote Schuur Hospital, Cape Town, South Africa.

Hence the correct answer is OPTION(B)

Note: Christiaan Neethling Barnard 8 November 1922 – 2 September 2001 was a South African cardiac surgeon who performed the world's first human-to-human heart transplant operation and the first one in which the patient regained consciousness.
On 3 December 1967, Barnard transplanted the heart of accident-victim Denise Darvall into the chest of 54-year-old Louis Washkansky, with Washkansky regaining full consciousness and being able to easily talk with his wife, before dying 18 days later of pneumonia.
