B. True Virtualization is a fundamental technology that underlies cloud computing. It enables the abstraction and virtualization of computing resources, such as servers, storage, and networks, allowing for the efficient allocation and utilization of these resources across multiple users or tenants. Cloud computing relies on virtualization to provide the flexibility, scalability, and isolation required to deliver on-demand services over the internet. Without virtualization, the key characteristics of cloud computing, such as resource pooling, rapid elasticity, and multi-tenancy, would not be possible. Virtualization enables the creation of virtual machines (VMs) or containers that can run multiple instances of operating systems and applications on a single physical server. Therefore, the statement is true. Without virtualization, there would be no cloud computing as we understand it today.
