Which statement is true about cloud computing?
The correct answer is C. It provides end-to-end server, application network service, and storage virtualization. Cloud computing abstracts and virtualizes physical infrastructure - servers, applications, networking, and storage - delivering them as pooled, on-demand services over a network.

Why each option
Cloud computing abstracts and virtualizes physical infrastructure - servers, applications, networking, and storage - delivering them as pooled, on-demand services over a network.
Cloud computing is available to individuals and organizations of any size, not limited to corporate usage only.
Cloud computing is defined by the provider owning and maintaining infrastructure, not the end user - the user merely consumes services.
Cloud computing is fundamentally built on end-to-end virtualization, abstracting physical servers into compute instances, physical network hardware into virtual networks, and physical disks into virtual storage. This virtualization layer enables the on-demand, scalable, and metered characteristics that define cloud computing. The statement accurately captures the underlying technical foundation of cloud platforms.
Cloud computing typically reduces total cost of ownership by eliminating capital expenditure on hardware and shifting to an operational expense model.
