Verified step by step guidance

Begin by identifying the primary function of each organ listed in the options: Kidneys, Spleen, Pancreas, and Liver.

Understand that the excretory system is responsible for removing waste products from the body and maintaining fluid balance.

Recognize that the kidneys are the main organs in the excretory system that filter blood to remove waste products and excess fluid, thus maintaining fluid balance.

Consider the role of the spleen, which is primarily involved in filtering blood and managing immune responses, not directly in fluid balance or waste detection.

Evaluate the functions of the pancreas and liver, noting that the pancreas is involved in digestion and blood sugar regulation, while the liver processes nutrients and detoxifies chemicals, but neither directly balances fluid or detects waste in the blood like the kidneys do.
