B

The answer to this question is A. Class C.

Explanation:

The IP address 191.168.0.1/27 is a Class C address. In Classful addressing, IP addresses were divided into classes based on their range of addresses. Class C addresses range from 192.0.0.0 to 223.255.255.255 and have a default subnet mask of 255.255.255.0.

The /27 subnet mask indicates that the first 27 bits of the IP address are used for the network portion, leaving 5 bits for the host portion. This means that the network address for this IP address is 191.168.0.0 and the broadcast address is 191.168.0.31.

To determine the class of an IP address, you can look at the first octet of the address. In this case, the first octet is 191, which falls within the range of Class C addresses.

It's worth noting that classful addressing is no longer used on the internet. Instead, Classless Inter-Domain Routing (CIDR) is used to allow for more efficient use of IP addresses and to accommodate the growing number of devices connected to the internet.
