Answer: Option D.
Step-by-step explanation:
Renal failure can be defined as the condition of kidneys in which the functional ability of kidneys to remove waste and balance fluids is loss.
Renal failure can lead to azotemia, high blood pressure, and nervous system problems.
In renal failure, blood vessels of kidneys get narrower that increases the amount of force through the blood vessels and results in hypertension (high blood pressure), Uraemic toxins produced during chronic renal failure contribute to central nervous system (CNS) injury, and Azotemia is severe cause of renal failure that allows elevation of blood urea nitrogen (BUN) and serum creatinine levels.
Hence, the correct option D.
