a mineralocorticoid hormones are secreted by the adrenal cortex.
b aldosterone is an example of a mineralocorticoid.
c aldosterone regulates sodium and potassium levels in the body.
d mineralocorticoids regulate carbohydrate metabolism in the body.

Explanation:

• Mineralocorticoids are indeed secreted by the adrenal cortex (so A is true).
• Aldosterone is a well - known mineralocorticoid (so B is true).
• Aldosterone acts on the kidneys to regulate sodium re - absorption and potassium excretion (so C is true).
• Glucocorticoids, not mineralocorticoids, are mainly involved in regulating carbohydrate metabolism. Mineralocorticoids are primarily for electrolyte balance.

Answer:

D. Mineralocorticoids regulate carbohydrate metabolism in the body.
