Selected Answer: B
A /23 subnet provides 510 total addresses, with 508 usable IPs (after excluding the network and broadcast addresses). This is enough to support 260 devices with minimal waste.

Selected Answer: B
C is wrong, that provides 1024 IP’s. A /23 provides 512, which is the best option here. So “B” is the answer
