Which situation most clearly requires real-time processing rather than batch processing?

Airline seat booking needs real-time processing, because availability must be updated immediately to prevent double booking. Payroll, annual depreciation and quarterly GST summaries are periodic tasks that can be accumulated and run in batches without any harm.

A reservation system must update availability instantly so the same seat is not sold twice, which needs real-time processing. Payroll, depreciation and quarterly summaries are periodic and can be handled in batches without loss.
