The correct choice is the anti-welding lubricant, which is designed to prevent the adherence of metals and reduce friction in situations where metal-to-metal contact occurs. This type of lubricant is particularly important in applications like electric saws, where blades experience high friction and potential welding due to heat generated during cutting. Anti-welding lubricants help maintain smooth operation, prolonging the life of the equipment and improving cutting efficiency.

Graphite lubricants are often used in low-speed applications and can create a messy residue, making them less effective for high-speed tools like electric saws. Oil-based lubricants can serve to lessen friction but may not specifically address the high-temperature conditions that can cause welding. Silicone spray lubricants provide a good surface coating and are used for general lubrication, but they are not tailored for the specific needs associated with electric saw applications involving metal parts that might weld together under heat.
