Correct Answer is C
Explanation
Central diabetes insipidus (CDI) can be caused by trauma or injury to the hypothalamus or pituitary gland, which disrupts the production or release of antidiuretic hormone (ADH). Other causes of CDI include tumors, infections, and certain medications.
Incorrect choices:
a. This choice is incorrect. Excessive fluid intake can lead to increased urine output, but it is not a cause of CDI.
b. This choice is incorrect. Kidney dysfunction is not a common cause of central diabetes insipidus.
d. This choice is incorrect. Hypersecretion of aldosterone would lead to sodium retention and increased fluid volume, which is not characteristic of central diabetes insipidus.
Correct Answer is C
Explanation
Gestational diabetes insipidus is a rare condition that occurs during pregnancy and is characterized by increased thirst and excessive urine production. It is caused by placental production of an enzyme that breaks down ADH.
Incorrect choices:

b. This choice is incorrect. Nephrogenic diabetes insipidus is not specifically associated with pregnancy and is not caused by placental factors.
