Selected Answer: D
Setting each access point on a different channel is important to avoid cross talk, which can cause interference and reduce the quality of the wireless signal. If multiple access points are set up on the same channel, they will compete for the same bandwidth, which can result in slower network performance. Additionally, having multiple access points on the same channel can cause interference and reduce the overall coverage area of the wireless network. By setting each access point on a different channel, it is possible to maximize network performance and ensure reliable wireless coverage.

D < A phenomenon by which a signal transmitted on one circuit or channel creates an undesired effect on another circuit. The goal of using different non-overlapping channels is to avoid the affects caused by channel utilization and interference.

B is the correct answer. Cross-talk is a term used in physical networking, it occurs when a signal transmitted on one copper pair radiates and interferes with transmission on another pair. In general it is best-practice to put multiple WAPs on different channels to avoid congestion/over-saturation.

Dude. Your unresearched confidence is astonishing. Your answer actually correctly states "radiate" to describe what crosstalk is. When physical networking cables (copper based) experience crosstalk, it's because the physical wires are acting like an antenna, RADIATING the signal being carried, which allows other nearby wires to pick up that signal. Hence the definition of crosstalk. Shielding and twisting wires is how crosstalk is managed in physical networks. You know what else radiates? WIFI antennae. On purpose. By design. Separate channels is how crosstalk is managed in WIFI.
