Which of the following is a method to bond materials to eliminate static electricity?

The method to bond materials to eliminate static electricity is a static comb. A static comb works by discharging static electricity from surfaces when you run it through those materials. It works on the principle of electrostatic induction; as the comb moves through the material, it can neutralize charge build-up and help bond the materials together, effectively reducing the risk of static discharge.

In contrast, heat application is generally not effective for bonding materials specifically to address static electricity; it might potentially alter the materials involved. Water spraying can reduce static to some extent as moisture conducts electricity, but it is not a bonding method in the same sense as a static comb. A magnetic field can influence certain materials, yet it does not inherently serve as a method to bond or eliminate static electricity. Thus, using a static comb is the most direct and practical approach for managing static charge on materials.
