Verified step by step guidance

Step 1: Begin by identifying the primary functions of the kidney. The kidney is a vital organ responsible for maintaining homeostasis in the body. Its main functions include filtration of blood to form urine, regulation of electrolyte balance, and regulation of blood pressure.

Step 2: Understand the processes involved in each kidney function. For example, filtration of blood occurs in the nephron, where waste products and excess substances are removed to form urine. Electrolyte balance is regulated by reabsorbing or excreting ions like sodium, potassium, and calcium. Blood pressure is controlled through mechanisms like the renin-angiotensin-aldosterone system.

Step 3: Evaluate the options provided in the question. Compare each function listed with the known roles of the kidney. The functions of regulation of electrolyte balance, filtration of blood to form urine, and regulation of blood pressure are all well-documented kidney functions.

Step 4: Consider the option 'Production of insulin.' Insulin is a hormone produced by the pancreas, not the kidney. This function is unrelated to the kidney's physiological roles.

Step 5: Conclude that the correct answer is 'Production of insulin,' as it is not associated with the kidney's functions. The other options are directly related to the kidney's role in maintaining homeostasis.
