They shift primary operational responsibility from the cloud customer to the service provider is the correct option.

The statement is correct because modern cloud platforms implement a shared responsibility model and the provider assumes primary responsibility for operating and securing the underlying infrastructure while the customer focuses on their data and applications. The exact split of duties changes between IaaS PaaS and SaaS, but in all cases the provider manages physical hardware networking and many platform services so operational burden shifts away from the customer.

They still rely on the same foundational components as traditional data centers even when those components are virtualized is not accurate because although cloud providers use similar low level hardware, they add strong abstraction automation and managed services that change how those components are deployed operated and secured.

They typically require far fewer physical servers and systems than comparable on-premises deployments is misleading because while customers can avoid running their own physical servers the cloud platform itself is built on very large scale physical infrastructure and the statement is not generally true as written.

They are commonly operated from a single physical site rather than across multiple locations is false because cloud providers purposely distribute services across regions and availability zones to provide resilience scalability and lower latency so single site operation would be contrary to normal cloud design.
