Verified step by step guidance

Step 1: Understand the role of hormones in regulating blood electrolyte levels. Electrolytes such as sodium, potassium, and chloride are essential for maintaining fluid balance, nerve function, and muscle contractions.

Step 2: Identify the organ responsible for producing hormones that regulate electrolytes. The adrenal gland is key here, as it produces aldosterone, a hormone that helps control sodium and potassium levels in the blood.

Step 3: Compare the functions of the other organs listed in the problem. For example, the thyroid gland primarily regulates metabolism through hormones like thyroxine, the pancreas produces insulin and glucagon to regulate blood sugar, and the pituitary gland controls various other endocrine functions but does not directly regulate electrolytes.

Step 4: Focus on the adrenal gland's role in the endocrine system. Aldosterone, produced by the adrenal cortex, signals the kidneys to reabsorb sodium and excrete potassium, directly influencing blood electrolyte levels.

Step 5: Conclude that the adrenal gland is the correct answer based on its specific function in electrolyte regulation, while the other organs listed have different primary roles in the body.
