Which of the following is NOT a feature of type 2 diabetes mellitus?

Correct option is B

Type 2 diabetes mellitus (T2DM) is characterized by insulin resistance and relative insulin deficiency. It is often managed with oral medications and lifestyle changes, and insulin is not always required. Therefore, the term “insulin-dependent diabetes mellitus” is more appropriate for type 1 DM, not type 2.
Explanation of options: (a) ✔ The most common type – T2DM accounts for over 90% of diabetes cases. (b) ✘ Insulin-dependent – Incorrect; insulin may be needed in advanced stages, but not initially. (c) ✔ Adult-Onset – Commonly appears in adults, although increasing in children now. (d) ✔ Endogenous insulin production is present – The body still produces insulin in T2DM.
