Explanation

Address 1 in the 802.11 frame header is defined as the Receiver Address (RA), which identifies the immediate destination - the device that should receive and process the frame off the wireless medium. Address 2 serves the opposite role: it is the Transmitter Address (TA), identifying the device that sent the frame. Address 3 is used for additional filtering, typically carrying the destination or source address depending on whether the frame is moving toward or away from the distribution system, and it does not represent the immediate receiver. Address 4 appears only in WDS (Wireless Distribution System) or mesh scenarios where a frame crosses between access points, making it irrelevant for identifying the primary receiving end.

Memory tip: Think of the addresses in order of immediacy - Address 1 is the first thing the receiving station checks to determine "is this frame for me?", so it naturally holds the receiver address.
