Explanation

Master-detail relationships enable Roll-Up Summary fields, which automatically aggregate child record data (Count, Sum, Min, Max) up to the parent record. Here, "New Runners" is the master (parent), while the TV, radio, print, and social campaigns are the detail (child) records - making their combined statistics visible and auto-calculated on the parent.

Why the distractors are wrong:

• A. Junction object - designed for many-to-many relationships (e.g., linking two unrelated objects), not parent-child aggregation
• B. Parent campaign field - the built-in Campaign "Parent Campaign" field uses a lookup, not a master-detail, so it does not support roll-up summary fields and cannot automatically aggregate statistics
• C. Lookup relationship - lookups establish a reference between records but do not support roll-up summary fields, meaning totals cannot be automatically calculated

Memory tip: Think "Master = Aggregates, Lookup = Just Links." If an exam question mentions rolled-up totals or aggregated statistics flowing from children to a parent record, that's your signal to pick master-detail.
