The correct answer to this question is:
Stacking order refers to how objects are stacked on top of each other in PowerPoint.
When you prepare a PowerPoint presentation, you may insert multiple objects on a slide, and these objects such as pictures, shapes, and text, etc appear in the stacking order. Stacking refers to placing objects in a slide one on top of another. In other words, the first object you draw on a slide appears at the bottom and the last object that you put on the slide appears at the top.
While the options are not correct because;
How objects are ordered in the rotation of animation is referring to aligning the objects, the size of the picture does not link with the stacking order, and also to delete objects from slide does not have any relation with stacking order.
