Which type of object-based storage can be used to store virtual machines?

The option indicating vVols is the correct choice because Virtual Volumes (vVols) represent a storage paradigm that allows for more granular control of storage resources in VMware environments. vVols integrate more deeply with the storage array, allowing for virtual machine (VM) operations to be managed at the VM level rather than at the datastore level. This means that each VM can have its storage configuration, simplifying tasks like snapshots and clones and enhancing performance.

In a vVols environment, storage policies can be created based on the characteristics and requirements of individual VMs, which is particularly beneficial for dynamic workloads. This modern approach allows for more efficient management of storage resources as it ties VM needs directly to the capabilities of the underlying storage systems.

While the other options represent important storage concepts within the VMware ecosystem, they do not provide the same level of integration with virtual machines as vVols. Targeting VM functionality and optimizing storage based on VM needs makes vVols the best choice for object-based storage specifically for virtual machines.
