The answer for the above question is D. Feldspar, Mica, Sulfur. 
Hydrothermal vents results from sea water percolating down through fissures in the ocean crusts in vicinity of spreading centers or subduction zones. They are important since they help regulate ocean chemistry and circulation, and also provide a laboratory in which scientists can study changes to the ocean.
