What part of the recurve limb holds the string?

The string notch is the correct response because it is specifically designed to hold the bowstring in place on the recurve limb. The string notch provides a secure point for the string to rest when the bow is strung, ensuring proper alignment and tension, which are crucial for effective shooting and maintaining the structural integrity of the bow.

The limb pocket is where the limbs are attached to the riser, and while important for the overall function of the bow, it does not hold the string itself. The riser is the central part of the bow that houses the grip and limb pockets, and the grip is where the archer holds the bow. Neither of these components directly interacts with the bowstring in the same way that the string notch does.
