b. This choice is incorrect. Type 2 diabetes mellitus involves insulin resistance and relative insulin deficiency, but not the autoimmune destruction of beta cells.

c. This choice is incorrect. Gestational diabetes mellitus occurs during pregnancy and is not characterized by autoimmune destruction of beta cells.

d. This choice is incorrect. Secondary diabetes mellitus is caused by other underlying medical conditions or factors and is not primarily characterized by autoimmune destruction of beta cells.

A. Type 1 diabetes mellitus. B. Type 2 diabetes mellitus. C. Gestational diabetes mellitus. D. Prediabetes.

Correct Answer is A

Explanation

Type 1 diabetes mellitus is an autoimmune condition in which the body's immune system attacks and destroys pancreatic beta cells, resulting in a lack of insulin production.

Incorrect choices:

b. This choice is incorrect. Type 2 diabetes mellitus is characterized by insulin resistance and impaired insulin secretion, but pancreatic beta cells are not completely destroyed.

c. This choice is incorrect. Gestational diabetes mellitus occurs during pregnancy and is not caused by autoimmune destruction of pancreatic beta cells.

d. This choice is incorrect. Prediabetes is a condition in which blood glucose levels are higher than normal but not high enough to be classified as diabetes. It is not characterized by autoimmune destruction of beta cells.
