Solution

Answer (b). Sodium rosinate

Shaving soaps contain glycerol to prevent rapid drying. While preparing these soaps, a gum called rosin is added to them. It forms sodium rosinate which lathers well. Laundry soaps contain sodium rosinate, sodium silicate, borax, and sodium carbonate.
Trisodium polyphosphate is an important filler added to detergent powders and liquid detergents.
