Answer: On-demand mode with DynamoDB Standard table.
The correct answer is B: On-demand mode with DynamoDB Standard table. This is because on-demand mode allows the table to automatically scale its capacity up or down based on the actual request traffic, which is ideal for unpredictable workloads. It prevents over-provisioning or under-provisioning issues, and helps in providing a cost-effective solution for variable traffic patterns. The Standard table class is selected to handle the anticipated moderate to high throughput efficiently.
