Explanation

Elasticity refers to the cloud's ability to automatically scale resources up or down based on demand - acquiring more resources when needed and releasing them when they are no longer required, which perfectly matches the scenario described.

Availability (A) is about ensuring a system remains accessible and operational with minimal downtime, not about scaling resources dynamically. Durability (C) refers to the long-term preservation and integrity of data, ensuring it isn't lost or corrupted. Reliability (D) describes a system's ability to consistently perform its intended function and recover from failures, rather than scaling resources on demand.

Memory Tip: Think of a rubber band - it stretches (scales up) when you need it and contracts (scales down) when you don't. "Elastic" behaves the same way, making Elasticity the perfect term for auto-scaling cloud resources. If you see keywords like "automatically acquire" and "release when no longer needed," that's always pointing to Elasticity.
