The correct answer is: A. transaction processing system.
A transaction processing system (TPS) is an information system that captures and processes data from day-to-day business transactions. TPSs are used to process routine, repetitive transactions such as sales, purchases, and payroll. They are typically used in industries such as banking, retail, and manufacturing.
The reservation system of Indian railways is an example of a TPS. It is used to process reservations for train tickets. The system captures data such as the passenger’s name, contact information, and travel dates. It then processes this data to generate a ticket.
The other options are incorrect because they do not describe the reservation system of Indian railways accurately.

C. Management controls system is a system that helps managers monitor and control their organization’s activities. Management controls systems typically include financial reporting, budgeting, and performance evaluation.
D. Expert system is a computer program that can make decisions or recommendations like a human expert. Expert systems are typically used in specialized fields such as medicine, law, and finance.
