A149
B153
C157
DAll except 149

Explanation

In a WDS point-to-point network, the backbone link requires both the Root AP and the Leaf AP to operate on the same channel so they can communicate over the wireless backhaul - if they are on different channels, they simply cannot hear each other. Since the Root AP is configured on channel 149, the Leaf AP must also be set to channel 149 (option A) to establish and maintain the backbone link.

Options B (153) and C (157) are incorrect because they are adjacent 5GHz channels, not the same channel as the Root AP; a mismatched channel would prevent the two APs from forming the WDS link entirely. Option D is the opposite of the correct principle - it lists every channel except the one that would actually work.

Memory tip: WDS backbone = same channel on both ends. Think of it like two walkie-talkies that must be tuned to the same frequency to talk - the Leaf AP must match the Root AP's channel exactly.
