उत्तर
All of these.
Explanation:
The image depicts a tough food or curry stain, a combination stain containing dried grease, oils, and strong organic plant dyes such as turmeric. Glycerine is applied first to soften and loosen the dried, crusty food residue on the fabric fibres; methylated spirit acts as a powerful organic solvent to break down stubborn colour pigments; and soap and water are used to thoroughly wash away the remaining oily grease.
