When disposing of computer equipment, which of the following can present an environmental hazard?

A bezel is typically made of plastic or metal and does not contain significant hazardous materials that would pose an environmental hazard during disposal.

A SATA cable is primarily made of plastic and copper wire, which are generally not considered significant environmental hazards compared to the materials found in CRTs.

A Cat5 cable is composed mainly of plastic insulation and copper conductors, similar to a SATA cable, and does not pose a significant environmental hazard during disposal.

CRT (Cathode Ray Tube) monitors contain hazardous materials such as lead in the glass, cadmium, mercury, and phosphors. These toxic substances can leach into the environment if not disposed of properly, posing a significant environmental hazard and requiring specialized recycling.
