A

B
gigantism
C

D

Explanation: 

Detailed explanation-1: -Acromegaly is a rare condition where the body produces too much growth hormone, causing body tissues and bones to grow more quickly. Over time, this leads to abnormally large hands and feet, and a wide range of other symptoms. Acromegaly is usually diagnosed in adults aged 30 to 50, but it can affect people of any age.

Detailed explanation-2: -When you have too much growth hormone, your bones increase in size. In childhood, this leads to increased height and is called gigantism. But in adulthood, a change in height doesn’t occur. Instead, the increase in bone size is limited to the bones of your hands, feet and face, and is called acromegaly.

Detailed explanation-3: -Acromegaly is a disorder that occurs when your body makes too much growth hormone (GH). Produced mainly in the pituitary gland, GH controls the physical growth of the body. In adults, too much of this hormone causes bones, cartilage, body organs, and other tissues to increase in size.

Detailed explanation-4: -Acromegaly is usually caused by a non-cancerous tumor in the pituitary gland called a pituitary adenoma. The tumor produces too much GH and raises the level of GH in the blood. Too much GH also raises the level of insulin-like growth factor-1 (IGF-1), a hormone produced in the liver that also promotes growth.

Detailed explanation-5: -Until now, an enlarged nose and face, a protruding mandible and forehead and thickened lips have been the facial characteristics that are superficially associated with acromegaly patients (6).
