Explanation

High availability (HA) is the cloud characteristic directly tied to reliability. It refers to systems designed to remain operational with minimal downtime, often achieved through redundancy, failover mechanisms, and geographically distributed infrastructure. Shared resources (A) describes resource pooling, rapid elasticity (C) refers to on-demand scaling, and hybrid (D) is a deployment model - none of these specifically address reliability.
