Choice ''b'' is correct. Batch processing of transactions will likely meet the data processing needs for a car repair company. Unique repairs would be performed, costs would be accumulated and then services would be billed during a distinct period when the vehicle is dropped off to the repair shop and returned to the owner. Batch processing will be adequate since it will normally not be necessary to have every transaction immediately recorded in the system as it occurs.Choices ''a'', ''d'', and ''c'' are incorrect. High volume businesses with multiple transactions that may originate from remote sites normally need an on-line real-time (OLRT) system to support their operations. In the three responses representing incorrect responses, OLRT is required since the same airline seat, theatre seat, or car cannot be sold/rented more than once at a simultaneous instant. Once the product has been sold/rented, the records must be immediately updated to reflect that. OLRT systems meet those needs.
