The correct file type needed for a destination system to find metadata about the segment integrated with an Amazon S3 activated campaign is the .json file. JSON, which stands for JavaScript Object Notation, is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. When integrating with services like Amazon S3, the .json format is commonly used to convey structured data and metadata due to its flexibility and compatibility with web services.

The other file types, while they each have their own distinct uses, are not typically suited for this purpose. Text files (.txt) lack structured formatting, making it difficult to retrieve complex metadata efficiently. Comma-separated values (.csv) files are primarily used for tabular data and may not adequately describe nested metadata structures. Zip files (.zip) are archive files which can contain multiple file types, but do not directly convey metadata on their own without an included format that contains that information, such as JSON or XML. Therefore, the .json file stands out as the most appropriate choice for providing detailed metadata for the segment in the context of an Amazon S3 campaign.
