Class B IP addresses are characterized by their range, which spans from 128.0.0.0 to 191.255.255.255. This means that any IP address falling within this range qualifies as a Class B address.

The IP address 132.12.0.0 falls between the specified range, making it a Class B address. Similarly, the address 190.65.2.0 also fits within the Class B range, as it starts with 190, well within the limits. Lastly, 172.16.0.1 is another Class B address because 172 falls under the Class B range as well (it lies from 128 to 191).

Each of these selected addresses fits the criteria that define Class B addresses due to their first octet values. Thus, the answer highlights several valid Class B addresses as per standard IP classification.
