Class B range is 128 to 191,
128 in binary:10000000.
191 in binary: 10111111.
An IP address which belongs to class B has the first two bits in the first octet set to 10.
So, 10xxxxxx is the answer.

Class B 10xxxxxx=1*2^7+0*2^6=128 class b range is 128-191.
So answer b is correct same as for class c like 110xxxxx.
=1*2^7+1*2^6+0*2^5=128+64=192 and class E range is 192-223 same for class D and class E and class A also.

In class B network 2 bits were fixed. That is 10, So option should be B.
