Question
Thermal paste is used between the CPU and heatsink to:
Options

Explanation
Thermal paste (also called thermal compound or thermal interface material) is applied between the CPU and heatsink to fill microscopic air gaps caused by imperfect surface contact. Air is a poor thermal conductor, so these gaps would trap heat. Thermal paste, being highly thermally conductive, bridges those gaps and maximizes heat transfer from the CPU to the heatsink. It does not act as adhesive (D), a fire retardant (C), or a lubricant for removal (A).
