Which of the following is NOT an available Social Account for Account Summary Reports?

In the context of Account Summary Reports, Snapchat is not considered an available social account. This is primarily because most reporting features and integrations within Marketing Cloud are designed to align with social platforms that provide robust analytics and advertising capabilities, such as Facebook, Twitter, and LinkedIn. These platforms offer extensive data and insights that marketers can use to evaluate the effectiveness of their social media strategies. Snapchat, while popular, has more limited reporting features and does not typically provide the same depth of insights as the other platforms listed. Therefore, it does not appear as an option within Account Summary Reports, differentiating it from the more commonly integrated social media accounts.
