192.168.10.0 ==> class c
Default subnet mask as
255.255.255.0
111111111.11111111.11111111.00000000
Need 12 host , where 2^4=16 and 12<16 so we accommodated 12 in 16 i.e, 4 bits
Borrow 4 bit and subnet become
11111111.11111111.11111111.11110000
255.255.255.240
Answer : C.

12 hosts can be accommodated in 2^4 = 16 hosts.
So, mask becomes:
1111 1111.1111 1111.1111 1111. 1111 0000.
= 255.255.255. (128+64+32+16).
= 255.255.255.255.240.
Hence, Option C is correct.
So, mask becomes:
1111 1111.1111 1111.1111 1111. 1111 0000.
= 255.255.255. (128+64+32+16).
= 255.255.255.255.240.
Hence, Option C is correct.
