Which type of class report field will display all expense lines for an expense report?

• A. Multi-Instance
• B. Single-Value
• C. Lookup
• D. Summary

Answer: (A)

The key idea is to choose a field type that can handle multiple related records. An expense report has many expense lines, so to show every line you need a field that can iterate over that collection. A multi-instance field is designed to output each related record, giving you a row for every expense line (date, amount, category, etc.).

Single-value would only return one item, not the full list. A lookup pulls in a value from a related object and isn’t meant to enumerate multiple lines. A summary would present an aggregate (like totals) rather than the full list of lines. So using a multi-instance field is the correct approach to display all expense lines for the expense report.
