Explanation

A Basic Service Set (BSS) is the term for a network consisting of a single wireless access point and the client devices associated with it - this is the fundamental building block of an infrastructure-mode wireless network, which is why B is correct. An IBSS (Independent Basic Service Set) is an ad-hoc network where clients communicate directly with each other without any access point, making A wrong. An ESS (Extended Service Set) scales beyond a single BSS by linking multiple access points together over a distribution system to form one larger logical network, so C describes something bigger than what the question asks. NSS (Number of Spatial Streams) is a MIMO-related term describing antenna streams, not a network topology at all, ruling out D.

Memory tip: Think "B for Basic, one Box" - one AP plus its clients = one Basic Service Set. When you see multiple APs joined together, that upgrades to Extended (ESS).
