To move the location of a sketch to a new plane after it has already been created, reattaching the sketch is the correct approach. Reattaching allows the user to select a new reference plane or face where the sketch can be relocated. This process ensures that all the constraints and dimensions defined in the original sketch remain intact, while updating its position based on the new reference. The reattach functionality effectively links the sketch to a different geometry, which is essential for maintaining the design's integrity.

The other choices, while they may sound plausible in some contexts, do not efficiently or correctly accomplish the intended task. Simply moving the sketch doesn’t provide a way to redefine its reference plane, and deleting the sketch would result in losing all the defined geometry, requiring recreation. Repositioning could imply a manual adjustment rather than a systematic reassignment to a new plane. Thus, reattaching is the most effective method for changing the sketch's location while preserving its parameters.
