B. 201.100.5.32
C. 201.100.5.64
D. 201.100.5.65
E. 201.100.5.31
F. 201.100.5.1


Answer: C
Explanation:
This is a C ip with a subnet mask of 255.255.255.240
the host 201.100.5.68/28 belong to the second subnet which is 201.100.5.64

this is determined by doing the following:

subnets?2^4-2=14
hosts?2^4-2=14
valid subnet range?256-240=16
16+16=32,16+32=48,16+48=64,64+16=80 and so as you can see the ip
201.100.5.68 belongs to the second subnet which is.64
