Answer - B - The components that prevent a processor from overheating are Heat-sink, Cooling Fan, and Thermal grease.

Key Takeaway: Heat sink is an object that absorbs and dissipates heat from another object using thermal contact. It is usually glued to the processor using Thermal glue. This way, the processor is protected from overheating. In systems that use high speed processors, an extra fan is fitted inside the chassis, generally beside the Motherboard I/O ports.
