Diabetes is the most common disorder associated with:Select the correct answer from the code given below:

1. A

   Kidney

   Option (a) claims diabetes is primarily associated with the kidney. While kidneys are often affected by long-term diabetic complications such as nephropathy, the primary organ responsible for the metabolic disorder is not the kidney.

2. B

   Gall bladder

   Option (b) claims diabetes is associated with the gall bladder. The gall bladder stores bile for fat digestion and does not regulate blood glucose levels or insulin production.

3. C

   Liver

   Option (c) claims diabetes is associated with the liver. Although the liver plays a major role in glucose storage and metabolism, it is not the primary endocrine gland whose dysfunction causes diabetes.

4. D

   Pancreas

   Option (d) states that diabetes is associated with the pancreas, which is the correct and official key. The pancreas contains the islets of Langerhans, where beta cells produce insulin, the vital hormone responsible for regulating blood sugar levels; a deficiency or resistance to this hormone leads directly to diabetes mellitus.

Summary. Official key is (d) because diabetes is fundamentally a metabolic disorder directly linked to the malfunction of the pancreas. Options (a), (b), and (c) point to the kidney, gall bladder, and liver respectively, which are secondary organs or involved in different bodily functions. The pancreas is uniquely responsible for insulin secretion, making its impairment the root cause of diabetes. Understanding this physiological distinction is essential for identifying the correct endocrine gland involved in blood glucose regulation.
