Explanation:
convert bit-length prefix to quad-dotted decimal representation,
then from it find the number of bits used for subnetting
you can find previously calculated number of subnets by separating subnets each having value of
last bit used for subnet masking
Find that your IP address is in which subnet, that subnet’s first address is network address and
last address is broadcast address.
Based on above steps the answer is option C
