Best answer
Right choice is (d) Frasch process

The best explanation: Frasch process is the industrial grade process of mining elemental sulfur from underground deposits. This is done by using pipelines and pumping superheated water and causing the molten sulfur to rise up which is then solidified. It was invented in 1894.
