What type of gainer dismount does an athlete use while executing off the end, piked?

A piked gainer off the end refers to a specific dismount technique where the gymnast performs a backward somersault with their body in a piked position while coming off the end of the apparatus. This means that as the gymnast leaves the platform or beam, they tuck their body forward at the hips, bringing their legs close to their chest and keeping their torso bent, which is characteristic of the piked position.

The other options involve different rotations or positions that do not align with the description of a simple piked gainer. For example, the 1/1, 2/1, and 3/1 dismounts indicate the number of rotations (full twists) combined with the gainer technique, which changes the complexity and execution requirements of the dismount. Since the question specifies a "piked" dismount executed off the end, the option that accurately describes this movement is indeed the piked gainer off the end. This shows a clear understanding of both the body position and the rotation being performed during the dismount.
