To solve these kind of questions, first approach should be finding network ID
Now given all the subnet masks, try to calculate Network ID for both the IP addresses and you will find out that
last octet of both the IP addresses are 113 and 91 respectively
With 224 in the last octet of Subnet mask, we are not able to get same Network ID as
113 is 01101111 and
91 is 01011011
with 0 mask we get 0 as network id
with 128 we get 0 as network id
with 192 we get 64 as network id
but with 224 we get different network ids
Hence option with 224 in the last octet is the correct answer.
