Resample changes the total number of pixels in an image.

Resample changes the total number of pixels in an image.

• A. Changes the color space
• B. Changes the total number of pixels in an image
• C. Deletes hidden layers
• D. Applies a filter to the whole image

Answer: (B)

Resampling changes the number of pixels in an image. When you resample, you adjust the image’s dimensions and resolution, which means you either add new pixels when scaling up or discard pixels when scaling down, so the total pixel count actually changes. This is different from changing the color space, which only affects how color values are represented without altering the number of pixels. It’s also different from deleting hidden layers or applying a filter, both of which operate on existing pixels or the document structure rather than changing the pixel grid. So resampling is the action that changes how many pixels the image contains.
