Point out the wrong statement.
O A process virtual machine instantiates when a command begins a process
O Guest operating systems in full virtualization systems are generally faster than other virtualization schemes
O Full virtualization requires that the host operating system provide a virtual machine interface for the guest operating system and that the guest access hardware through that host VM
O All of the mentioned choice are wrong

Full virtualization requires that the host operating system provide a virtual machine interface for the guest operating system and that the guest access hardware through that host VM

Explanation:

A process virtual machine instantiates when a command begins a process, hence this option is correct. Also, In full virtualization systems, guest operating systems are faster than other virtualization schemes. However, guest operating systems on paravirtualization systems must undergo porting in order for it to work effectively with the host interface, hence the chosen option is wrong as it implies so for full virtualization.
