Best answer
Right option is (c) Lime

Explanation: The fresh lime is slaked at site of work and mixed thoroughly with a sufficient quantity of water in a tub. It is then screened through a clean cloth. The clean gum dissolved in hot water is then added at the rate of 20 Newton per metre cube of lime. The rice may be used in place of gum.
