unpredictable & When traffic spikes occur they will happen very quickly. So how on - demand will take care of quick traffic and unpredictable spikes. Who knows how much capacity required?

A On-demand mode is a good option if any of the following are true: You create new tables with unknown workloads. You have unpredictable application traffic. You prefer the ease of paying for only what you use. Provisioned mode is a good option if any of the following are true: You have predictable application traffic. You run applications whose traffic is consistent or ramps gradually. You can forecast capacity requirements to control costs. https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.ReadWriteCapacityMode.html

Why not is C?

If the question mention that a specific fixed size is needed at all time, then C would have been the answer. Since no minimum size was mentioned A is the best option.

Because you don't know the traffic DynamoDB on-demand is useful if your application traffic is difficult to predict and control, your workload has large spikes of short duration

This might also be helpful on why not C. For tables using provisioned capacity, DynamoDB delivers automatic scaling of throughput and storage based on your previously set capacity by monitoring the performance usage of your application. If your application traffic grows, DynamoDB increases throughput to accommodate the load. If your application traffic shrinks, DynamoDB scales down so that you pay less for unused capacity.

'The table will not be used on most mornings and in the evenings, the read and write traffic will often be unpredictable'. Table will not be used in the AMs.. so provisioned capacity while being cheaper still may end up with huge billing so on-demand sounds more correct.. what ya say?

https://aws.amazon.com/blogs/aws/amazon-dynamodb-on-demand-no-capacity-planning-and-pay-per-request-pricing/: "DynamoDB on-demand offers simple pay-per-request pricing for read and write requests so that you only pay for what you use, making it easy to balance costs and performance. For tables using on-demand mode, DynamoDB instantly accommodates customers’ workloads as they ramp up or down to any previously observed traffic level. If the level of traffic hits a new peak, DynamoDB adapts rapidly to accommodate the workload." A is the answer
