Verified step by step guidance

Understand the role of aldosterone: Aldosterone is a hormone produced by the adrenal glands that plays a crucial role in regulating sodium and potassium levels in the body, as well as blood pressure.

Identify the segments of the renal tubule: The renal tubule consists of several segments, including the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct.

Determine where aldosterone acts: Aldosterone primarily acts on the distal convoluted tubule and the collecting duct. It increases the reabsorption of sodium and water, and the excretion of potassium, which helps regulate blood pressure and fluid balance.

Evaluate the options: Given the options, the distal convoluted tubule is the correct segment where aldosterone exerts its influence, as it is directly involved in sodium reabsorption under the influence of aldosterone.

Conclude with the correct answer: Based on the understanding of aldosterone's function and its site of action, the distal convoluted tubule is the segment influenced by aldosterone.
