Correct answer: 2 only — "Databases allow many users to access data simultaneously."
Why:
- Databases are designed for concurrent access: they provide transaction handling, locking, isolation levels and concurrency control so multiple users can read and write safely without corrupting data.
- "Databases are cheaper." — not generally true and not a reason for better concurrency.
- "Spreadsheets cannot store words." — false; spreadsheets can store text.
- "Spreadsheets are only for single users." — misleading; many spreadsheets can be shared, but they lack robust concurrency control and are poorly suited for many simultaneous writers.
