Correct Answer is C
Explanation
A. Incorrect. Acute renal failure is not a chronic condition; it is an acute condition that develops rapidly and is typically reversible with prompt treatment.
B. Incorrect. While long-term uncontrolled diabetes can lead to chronic kidney disease, acute renal failure is not caused by chronic kidney damage related to diabetes.
C. Correct. Acute renal failure, also known as acute kidney injury (AKI), is characterized by a sudden and temporary loss of kidney function. It is often caused by factors such as decreased blood flow to the kidneys, kidney damage, or obstruction of the urinary tract.
