Correct Answer

Explanation

Aluminium hydroxide is not commonly used in the dyeing industry. Instead, metal salts such as aluminum sulfate (alum) are more frequently employed as mordants in the dyeing process. A mordant is a substance that helps fix or bind a dye to the fabric, improving colorfastness and the overall quality of the dyeing.
