To solve the matching question, we need to correctly link each disease (List-I) with their corresponding characteristics (List-II). Here is the breakdown of each disease and its effects:

Exophthalmic goiter: Also known as Graves' disease, this is an autoimmune disorder that involves an overactive thyroid (hyperthyroidism) and is characterized by symptoms such as protruding eyeballs. Therefore, this matches with "Hyper secretion of thyroid hormone & protruding eye balls." - from List II (III).

Acromegaly: This condition is caused by excessive secretion of growth hormone, usually from a benign tumor in the pituitary gland, leading to enlarged features (bones, especially in the hands, feet, and face). Thus, it corresponds with "Excessive secretion of growth hormone." - from List II (IV).

Cushing's syndrome: This syndrome is the result of prolonged exposure to high levels of the hormone cortisol. It features symptoms including obesity majorly centered around the abdomen and upper back, moon face, and hyperglycemia. Therefore, it fits "Excess secretion of cortisol, moon face & hyperglycemia." - from List II (I).

Cretinism: This is a condition arising from the deficiency of thyroid hormone in childhood, which causes impaired neurological function, stunted physical growth, and possibly other symptoms. It matches with "Hypo-secretion of thyroid hormone and stunted growth." - from List II (II).

Now, compare these with the available options:

• Option A - A-I, B-III, C-II, D-IV - Incorrect because the descriptions do not match correctly.
• Option B - A-IV, B-II, C-I, D-III - Incorrect because the descriptions do not match correctly.
• Option C - A-III, B-IV, C-II, D-I - Incorrect because of an incorrect assignment for C and D.
• Option D - A-III, B-IV, C-I, D-II - Correct, as all labels are correctly matched according to the disease and characteristic explanations provided above.

Therefore, the correct answer is Option D.
