Explanation

Directional antennas do not universally increase WLAN coverage area; they concentrate signal energy in a specific direction, which increases range in that direction but simultaneously reduces coverage in all other directions - narrowing the overall area served rather than expanding it. The statement is further invalidated by the phrase "in any country," because most countries impose regulatory limits on EIRP (Effective Isotropic Radiated Power), meaning that using a higher-gain directional antenna typically requires reducing transmitter output power to remain compliant, which can offset or eliminate any range gain.

Why A (True) is wrong: Directional antennas trade breadth for depth - you get a longer "beam" but a much narrower coverage footprint. Net coverage area typically shrinks, not grows.

Memory tip: Think of directional antennas like a flashlight versus a lamp. A flashlight shines farther in one direction, but the room is darker overall. More range ≠ more area - and regulators control how bright your flashlight can be anyway.
