B. lscpu The lscpu command is used to display information about the CPU architecture and the system topology on Linux systems. It provides information about the number of CPUs, cores, and threads, the architecture, clock speed, and cache size. If the system supports virtualization, it should be reflected in the output of the lscpu command. The other options are not relevant for checking virtualization support: dmidecode -s system-version is used to retrieve the version number of the system's BIOS or UEFI firmware. sysctl -a is used to display all system control parameters, including both kernel parameters and sysctl settings. cat /sys/device/system/cpu/possible does not exist, it should be /sys/devices/system/cpu/possible. This file provides information about the maximum number of CPUs that can be configured for the system, but does not indicate whether the system supports virtualization.
