the subnet mask is 192 that means 11 000000 , so 2 bits from HID taken for subnets there are 4 subnets possible like 00, 01, 10 and 11 so for 00 broadcast address is 195.37.5. 63 , for 01 broadcast address is 195.37.5. 127, for 10 broadcast address is 195.37.5. 191, for 11 broadcast address is 195.37.5. 255. but option c says 195.37.5.31 which not match with anyone hence option C is not a broadcast address in any of the sub network .
