Complete answer:
Let us study the option to find out the solution:

Option A: Willem Kolff in 1945 developed a drum kidney for the treatment of kidney dialysis on a 67 years old person who has acute kidney failure and he got successful in treating him and the patient got discharged with a normal kidney function. Willem Kolff invented the kidney dialysis machine. Therefore, this is the correct option.

Option B: Willem Einthoven in 1895 was the inventor of the first particle electrocardiogram, as he was a renowned physiologist and a Dutch physician and in 1924, he was awarded the Nobel prize in physiology and medicine. Therefore, this is an incorrect option.

Option C: Willhelm roentgen was the person who earned the first Nobel prize in detecting the wavelength range of electromagnetic radiation that is known as X rays as well as roentgen rays as he was a German mechanical engineer and a physicist. Therefore, this is an incorrect option.

Option D: Rene Laennec in 1816 was the inventor of the stethoscope, and he used his invention in treating chest conditions in his time as he was a great French physician and musician. Therefore, this is an incorrect option.

Hence, the correct answer is option (A)

Note: Kidney dialysis machines help our body to balance the extra salt and water and also prevent them from getting deposited in the body, and help in controlling blood pressure. Kidney dialysis is generally recommended when patients develop end stage kidney failure (around 80 to 90% of kidney function is lost.)
