Never see there is a subnet mask of /33

Mod Fix. Thx!!!

Oh common guys it's A

The correct answer is A. The CIDR value /33 should be /32 instead.

The cause of the issue is that the prefix length specified in the IP address/netmask is invalid. In the command ip address add 192.168.168.1/33 dev eth0, the prefix length is specified as /33, which is not a valid prefix length. In IP networking, the prefix length specifies the number of bits in the network portion of the address. For example, a netmask of 255.255.255.0 corresponds to a prefix length of /24, because the first 24 bits of the address are used for the network portion. The valid prefix lengths depend on the address class and type. For IPv4 addresses, the prefix length must be between 0 and 32. A prefix length of 33 is not valid, and that is why the command produced an error. To fix the issue, the systems administrator should use a valid prefix length in the IP address/netmask, such as /32 if the address is a host address or /24 if the address is a network address. For example: ip address add 192.168.168.1/32 dev eth0
