Question

when removing the background from an image, what occurs to the part of the image highlighted in pink? it remains as part of the image. it is deleted from the image. it becomes the border around the image.

Explanation:

When removing the background from an image, the highlighted part (foreground) remains as part of the image. Deleting it would defeat the purpose of background - removal (which is to keep the subject), and it doesn't become a border as that's not a typical outcome of background - removal operations.

Answer:

It remains as part of the image.
