Which social media feature allows users to share temporary moments?

The correct choice is the feature that allows users to share temporary moments, which is known as a "Story." This feature is popular across several social media platforms, such as Instagram, Facebook, and Snapchat. Stories are designed for sharing content that is temporary, disappearing after a set period, typically 24 hours. This format encourages spontaneity and provides a way for users to share their day-to-day experiences or highlights without cluttering their permanent profiles.

The timeline is a feature that displays a user's posts in a chronological order, allowing others to see a history of shared content. A post generally refers to any content shared on a social media platform, whether it’s text, images, or videos, and remains on the user's profile unless deleted. An event refers to a scheduled occasion that users can create and invite others to join, which is not focused on temporary content sharing. Each of these features serves different purposes within the social media landscape, highlighting why "Story" is the most suitable choice for sharing temporary moments.
