Which of the following accurately describes "snap to guide" in Adobe Animate?

The correct answer highlights the purpose and functionality of "snap to guide" in Adobe Animate. This feature involves the use of guidelines that assist in aligning objects within the stage. These guidelines are non-printing, meaning they do not appear in the final output or printed version of the project, ensuring that they serve only as visual aids in the design process.

Additionally, guidelines are movable, allowing users to position them as needed to create precise layouts or alignments. The option mentions that they can also be modified or locked, which is crucial for maintaining a stable design environment. Locking a guideline prevents it from being accidentally moved while working on the project, providing better control over the arrangement of elements within the animation.

The other options describe concepts that do not align with the specific functionality of snap to guide. For example, guidelines for animation timing pertain to different aspects of animation mechanics and are not related to visual alignment. Snapping to the grid involves snapping objects to a defined grid layout rather than to guidelines. Meanwhile, a feature for printing guides does not accurately depict the nature of guidelines in the context of Adobe Animate, as those guidelines are primarily for on-screen use rather than for printing purposes.
