Which of the following is a function of the bones?

  1. Facilitating digestion

  2. Lending support to body structures

  3. Producing insulin

  4. Regulating blood sugar levels

The correct answer is: Lending support to body structures

Bones play a critical role in the human body by providing structural support, allowing us to move, and protecting vital organs. The other options are incorrect because bones do not facilitate digestion (A) or produce insulin (C) or regulate blood sugar levels (D). These functions are performed by different organs such as the digestive system and the pancreas. Therefore, the correct answer is B because the primary function of bones is to support body structures.
