D. To provide a source of tendon nutrition from synovial fluid

Explanation
The digital flexor sheath has three main functions. First, it facilitates smooth gliding of the tendons, allowing for efficient movement of the fingers. Second, it acts as a fulcrum, providing a mechanical advantage that enhances the strength and efficiency of finger flexion. Lastly, the sheath provides a source of tendon nutrition by supplying synovial fluid, which nourishes and lubricates the tendons, promoting their health and function.
