Assuming Hypothesis B to be correct, which of the following endocrine disorders would cause hypertension that could NOT be rectified by physiologically normal kidneys? A.) An excess of aldosteroneB.) An excess of glucagonC.) A shortage of thyroxineD.) A shortage of insulin

Option (A).

Explanation:

Endocrine glands directly secrete their products in the blood and absorbed by the body. The deficiency or excess secretion of a hormone can cause a characteristic disease in an organism.

The main function of aldosterone is the reabsorption of sodium and water thus increase the blood pressure. The excess secretion of aldosterone causes hypertension as it increases the blood volume.

Thus, the correct answer is option (A).
