Answer & Solution
Correct answer: C. One or more discrete data centers with redundant power, networking, and connectivity, within a single AWS Region
An AZ is one or more discrete data centers inside a single Region, each with independent power, cooling, and networking. AZs are isolated from each other so a single-AZ failure doesn't propagate.
