Explanation

B is correct because Elastic Cloud Servers (ECS) are themselves virtual machines running on a cloud provider's hypervisor, and standard ECS instances do not expose the hardware virtualization extensions (such as Intel VT-x or AMD-V) needed to support a guest hypervisor. Without those extensions being passed through, installing virtualization software to create secondary VMs (nested virtualization) is not supported on a typical ECS.

Why A is wrong: Although ECS instances offer significant flexibility - you can install most operating systems, applications, and services - this freedom does not extend to nested virtualization. The cloud platform intentionally restricts this capability for security isolation, resource integrity, and performance predictability across tenants.

Memory tip: Think of an ECS as a tenant apartment - you can furnish it however you like, but you cannot subdivide it into new apartments (nested VMs) because the building's structural rules (the hypervisor layer) don't allow it. "ECS = already virtual, so no virtualizing inside the virtual."
