Which statement about rosters is true?

Which statement about rosters is true?

• A. It must be a comma-separated values (CSV) file
• B. It can be a PDF file
• C. It can be a Microsoft Word document
• D. It can be an image file

Answer: (A)

Rosters are best kept in a structured, machine-readable format so the data can be easily imported, validated, and analyzed. A CSV file fits that need: it encodes data as rows and columns with a simple delimiter, preserving values like names, IDs, units, and roles in a predictable way. This makes it straightforward to load into spreadsheets or databases, run checks, and merge with other datasets. Other formats like PDF, Word documents, or image files are designed for human consumption and fixed layouts, not for data manipulation. PDFs freeze layout and are hard to extract reliably; Word documents can include formatting and styles that complicate automated parsing; image files are just pictures, offering no text data to extract. Therefore, the statement about rosters being in CSV form is the most practical and widely compatible choice for data handling.
