Answer: Utilize on-demand capacity mode for the DynamoDB table.
The correct answer is A: Utilize on-demand capacity mode for the DynamoDB table. This is because on-demand capacity mode automatically adjusts to unpredictable traffic spikes, which helps in managing the varying traffic during the evenings. It also minimizes costs when the table is not being used, such as in the mornings, because you only pay for the read and write units you consume.
