Given the data below: In which of the following file formats is the data presented?

XLS is a proprietary file format used by Microsoft Excel, which stores data in a structured spreadsheet format, not typically a plain text, comma-separated format.

CSV (Comma Separated Values) is a plain text file format that stores tabular data in an organized way, where each line in the file represents a data record and each field within a record is separated by a comma or another delimiter. This format is widely used for importing and exporting data between different applications due to its simplicity.

RTF (Rich Text Format) is a document file format that supports text formatting, images, and other rich content, not a simple delimited data format.

XML (Extensible Markup Language) is a markup language for encoding documents in a format that is both human-readable and machine-readable, using tags to define data elements, which is different from a simple delimited file.
