The suggested answer is B.
When configuring a workstation to be used as a VM host, it is important to enable the necessary hardware virtualization features. One of the key components for modern virtualization is the Trusted Platform Module (TPM), which provides hardware-based security functions. Enabling TPM ensures that the system supports secure boot and hardware virtualization, which are often necessary for creating and running virtual machines. The other options, such as disabling the BIOS password, enabling multithreading, or enabling Fast Startup, do not directly address the inability to create VMs and are not relevant to this issue.
