Question

this separates a filename from its extension when exporting or saving an image.

○ period

○ hpyhen

○ underscore

○ hashtag

Explanation:

In computer systems, when naming files (including images), the period (.) is used to separate the filename from its extension. For example, in "image.jpg", "image" is the filename and "jpg" is the extension, separated by the period. A hyphen (-) is used for joining words or indicating ranges. An underscore (_) is often used in filenames to replace spaces. A hashtag (#) has different uses like in social media for tagging topics but not for separating filename and extension.

Answer:

Period
