Why each option

vSphere HA and Fault Tolerance are the two features designed specifically to protect virtual machines and their data against physical host failures.

AVirtual Volumes

Virtual Volumes (vVols) is a storage integration framework that abstracts VM storage on external arrays but provides no host-failure protection or mechanism to prevent data loss from a crashed server.

BEnhanced vMotion Capability

Enhanced vMotion Capability enables live migration of VMs between hosts including those with local storage, but it is a planned migration tool and does not protect against unplanned host failures or prevent data loss.

CHigh AvailabilityCorrect

vSphere High Availability monitors all ESXi hosts in a cluster and automatically restarts protected virtual machines on surviving hosts within minutes when a host failure is detected, limiting data loss and downtime from a crashed server.

DFault ToleranceCorrect

vSphere Fault Tolerance maintains a continuously synchronized secondary VM on a separate host using vLockstep technology, so if the primary host crashes the secondary instantly takes over with zero data loss and zero downtime.
