Solution
The correct option is A Increase in aldosterone levels
Increase in both aldosterone levels and ADH levels, causes an increase in sodium reabsorption in DCT.
When both hormones are present in the blood, all the sodium ions in the filtrate are reabsorbed. Retaining sodium ions raises the osmotic pressure of the blood and reduces the water loss from the body.
However, aldosterone can also influence the production of ADH.
Hence, the appropriate answer here is increase in aldosterone levels.
