Answer:
C. 134.67.112.23
Step-by-step explanation:
A computer with the IP address of 134.67.89.12 and a subnet mask of 255.255.0.0 has a network address of the form:
134.67.0.0
This is obtained by retaining those sections of the ip address for which the corresponding subnet mask element is 255.In this case subnet mask is 255 for ip address components 1 and 2 or in other words the network address contains 134.67. Among the given options only 134.67.112.23 has the same network address.
