The correct answer is (B) Mordant is a metallic ion or salt added to the dye bath to make dyes more colorfast by forming a bridge between the dye and the fiber.

A mordant is a substance, usually in the form of a metallic ion or salt, that is used in the dyeing process to improve the colorfastness of dyes. When a mordant is added to the dye bath, it forms a chemical bond or bridge between the dye and the fibers of the material being dyed. This bond helps the dye molecules adhere more firmly to the fibers, resulting in enhanced colorfastness and resistance to fading or washing out.

Mordants can also influence the color of the final dye by interacting with the dye molecules and modifying their chemical structure. Different mordants can produce different shades or tones of color, even when using the same dye.
