Name a commonly used raster graphic design software.

Adobe Photoshop is a widely recognized raster graphic design software that excels in editing and creating images made up of pixels. It provides a vast array of tools and features that allow users to manipulate photos, create complex graphics, and apply a variety of effects. The software is specifically designed for raster graphics, which are composed of a grid of individual pixels, making it ideal for tasks such as photo editing, digital painting, and designing raster-based artwork.

In contrast, the other options are more suited for different types of design tasks. Adobe InDesign is primarily used for page layout and typesetting, making it better suited for print design and publishing. Microsoft Publisher is a desktop publishing application focused on creating publications, flyers, and brochures rather than pixel-based graphics. Sketch, while a powerful tool for user interface design and vector graphics, is not primarily classified as raster graphic design software.
