As an experienced Snapchat user, you know that one of the valuable metrics that only Snapchat can offer is: A Number of views B Story fallout ratio C Average percentage viewed D Watch time

The correct answer is B. Story fallout ratio.<br /><br />The story fallout ratio is a unique metric that Snapchat provides, which measures the percentage of users who view a story and then continue to view subsequent stories in the same session. This metric is valuable because it helps creators and businesses understand how engaging their content is and how well it retains viewers' attention throughout the story session.<br /><br />Option A, Number of views, is a common metric provided by many social media platforms, not just Snapchat. Option C, Average percentage viewed, is not a standard metric provided by Snapchat. Option D, Watch time, is also a common metric provided by many social media platforms, not just Snapchat.<br /><br />Therefore, the correct answer is B. Story fallout ratio.
