To determine which program Shalin should use to open the file named "old_site.tiff," we need to consider the file format and the capabilities of different design software.

The ".tiff" file extension typically indicates that the file is saved in the Tagged Image File Format, which is a common format for high-quality images.

Option A: Inkscape is a vector graphics editor that is better suited for working with scalable graphics and is not the best option for raster images like ".tiff" files.

Option B: Illustrator is a vector graphics editor, similar to Inkscape, and is primarily used for creating and editing vector-based artwork. While it can open ".tiff" files, it might not be the most suitable program for this particular file format.

Option C: Sketch is a digital design tool commonly used by macOS users. While Sketch is great for designing user interfaces and creating vector graphics, it may not be the best choice for opening ".tiff" files.

Option D: Photoshop is a powerful raster graphics editor developed by Adobe. It is widely regarded as the industry standard and can handle various image formats, including ".tiff" files.

Considering the file format and the capabilities of different design programs, Shalin should open the "old_site.tiff" file in D. Photoshop.
