Best answer
Right option is (c) 1879

To explain: In 1879, German chemist Carl F. Dahl developed the Kraft (sulfate) method of pulping wood. The process was essentially a modification of the soda process, but instead of sodium hydroxide, sodium sulfate was the major chemical used as the cooking liquor.
