How will the animation be rendered using the provided keyframes code?

The correct answer reflects the specific sequence and color changes defined within the keyframes in the provided code. In keyframe animations, each keyframe specifies a certain style at a particular time during the animation duration. If the code specifies that the animation begins with blue, transitions to purple, and then changes to red by the end of the specified duration, then this answer accurately describes that progression.

The structure of keyframes allows for transitions to be defined quite explicitly. Thus, if the keyframes indicate a color change that unfolds in this specific order, the animation will execute as described in the choice. Understanding the behavior of keyframes is critical in this context, as they dictate the timeline and the changes in style that occur based on the script.

In contrast, other options either misinterpret the transitions or the timing of the animation. For example, if an animation is set to change color, stating it remains purple would not align with how the keyframes were structured if there was indeed a transition back to red.
