Question
In WLAN networks, omnidirectional antennas are mostly used in point-to-multipoint communication hubs because of their non-directional nature, while directional antennas are suitable for long-distance communication because of their directional nature.

Explanation
A (True) is correct because both statements accurately describe real-world antenna usage in wireless networks. Omnidirectional antennas radiate signal equally in all horizontal directions, making them ideal for access points that must serve multiple clients simultaneously - the classic hub-and-spoke WLAN topology. Directional antennas concentrate signal energy in a narrow beam, which extends range and reduces interference, making them the standard choice for point-to-point wireless bridges across long distances (e.g., building-to-building links).
B (False) is wrong simply because there is no error in either claim - both halves of the statement are technically sound and consistent with how antenna types are deployed in practice.
Memory tip: Think of omnidirectional as a lighthouse (shines everywhere for all ships nearby) and directional as a flashlight (focused beam to hit one distant target). Hubs need lighthouses; long-haul links need flashlights.
