What is a benefit of opening files as Smart Objects in Photoshop?

Opening files as Smart Objects in Photoshop has significant benefits, primarily the ability to edit them multiple times without the risk of losing image quality. When a file is converted to a Smart Object, it retains its original data in the background, which means any transformations or edits you apply to the Smart Object—such as scaling, rotating, or applying filters—do not permanently alter the original pixel data. This non-destructive editing approach allows for greater flexibility and creativity, as adjustments can be made at any time, and changes do not degrade the quality of the image.

For instance, you can resize a Smart Object for a composition and later decide to increase its size again without concern over pixelation or loss of clarity. This proficiency in maintaining image integrity is especially crucial when working on high-resolution projects or preparing images for print.

In contrast, other options fail to reflect the actual capabilities of Smart Objects. They do not only open in read-only mode; rather, they allow for extensive editing. While they might involve some degree of file size increase due to the additional data they maintain, the claim that they significantly decrease file size is not accurate. Lastly, Smart Objects are designed precisely to be resized without quality loss, so the assertion that they cannot be resized doesn't align
