Answer :

When working with text boxes in software like Microsoft PowerPoint, the tab that contains settings for applying shadows and 3D rotation to objects is the "Effects" tab.

Here's how you can access this tab and apply shadows and 3D rotation:
1. Click on the text box or object you want to apply the effects to.
2. Go to the "Format" tab in the menu bar.
3. Look for the "Effects" group within the Format tab.
4. Within the Effects group, you will find options to apply shadows, reflections, glows, bevels, and 3D rotation to the selected object.

By navigating to the "Effects" tab, you can enhance the visual appeal of your text boxes by adding shadows and creating a 3D effect, making your presentation more dynamic and engaging for your audience.
