Answer: B. Elasticity, E. Pay-as-you-go pricing

The correct answers are B (Elasticity) and E (Pay-as-you-go pricing). Elasticity allows the company to scale its infrastructure up or down as demand fluctuates, which is crucial for handling seasonal sales spikes without overprovisioning during low demand periods. Pay-as-you-go pricing ensures that the company only pays for the resources they use, which is beneficial for unpredictable demand, as they can avoid large upfront investments and only pay for the resources they actually need.
