Solution

An increase in the concentration of plasma potassium causes an increase in the secretion of aldosterone.

Here's the step-by-step explanation:

  1. The concentration of potassium in the body is tightly regulated by the kidneys.

  2. When the concentration of potassium in the blood (plasma potassium) increases, it is detected by cells in the adrenal glands.

  3. These cells respond by increasing the secretion of the hormone aldosterone.

  4. Aldosterone acts on the cells of the kidney tubules and stimulates them to excrete more potassium into the urine.

  5. This helps to bring the concentration of potassium in the blood back down to normal levels.

So, the correct answer is b) secretion of aldosterone.
