An online gift retailer adds extra virtual machines and storage for the December shopping season and removes them in January. December's Azure bill is far higher than February's, although the subscription itself never changed. Which characteristic of Azure pricing explains the difference?

1. A. Azure follows a consumption-based model: the company pays for the resources used during each billing cycle, so the bill rises and falls with actual usage ✓ A
2. B. Azure recalculates the subscription's tier at the end of each month, and December was billed at a higher tier than February 💬 B
3. C. Azure charges for the peak capacity the subscription could have used during the billing cycle, whether or not that capacity was actually used by any workload 💬 C
4. D. Azure bills a per-deployment fee for each resource created or removed, so the invoice reflects how many deployments were made during the cycle 💬 D
