Halide in soldering refers to which of the following?

Explanation:
A halide is any compound that contains a halogen element (such as chlorine, bromine, fluorine, or iodine). In soldering, halides are used in fluxes as activators to help remove and prevent oxide layers on metal surfaces. This cleaning action exposes clean metal so the solder can properly wet and form a strong joint. The term halide, therefore, points to the chemical species containing halogens rather than to a metal alloy, a generic flux, or a desoldering solvent, which is why it best fits the concept described.
