C. Relational database
A relational database is the best choice for transactional data that: Follows a consistent schema (structured data). Is cross-referenced, meaning relationships between tables are required (e.g., customer records linked to purchase history). Supports ACID (Atomicity, Consistency, Isolation, Durability) properties, which are essential for ensuring data integrity in transactional systems.
