Finding the Range of Valid IP Addresses in a subnet: One more than the subnet number - one less than the broadcast address.
Since address 192.168.1.255 is a broadcast address, B is the correct answer.
Please read Chapter 5 in the Cisco Press ICND1 book. It has some great "logic" you should read!

Thank you, Hondabuff and special thanks to Abraham.
Your second extended answer is much better than the "end of story" kind of rhetoric. And my appeal to logic wasn't a personal attack, just a question if a valid ip directed broadcast address falls under category of IP address or is it rather a non IP-address or non valid ip address like 226.256.1.1
I have demonstrated before that in certain circumstances this broadcast would be forfarded into directly connected subnet with a destination MAC address FF-FF-FF-FF-FF-FF.
In some simlets here, for example QID:S27 you can find no ip directed-broadcast in the configuration output what makes sence only if ip directed broadcast was enabled by default on the router.
