Dealers must provide:

The correct answer is Stock, purchase, sale, import, export info. Regulatory acts often require dealers to maintain comprehensive records covering all aspects of their business operations. This includes inventory levels, procurement details, sales transactions, and any cross-border movements of goods (import/export). This extensive record-keeping ensures transparency, facilitates oversight, and helps prevent illicit trade or non-compliance. Options B (Only sales invoices), C (Only bank records), and D (Only annual data) are incorrect because they represent incomplete sets of information. Regulators typically demand a holistic view of a dealer's activities for effective monitoring and enforcement.
