Best answer
Right answer is (a) Solvent extraction

The best explanation: Solvent extraction is the method which is used to remove the oil from the algal biomass, so, that it can be further processed, whereas, water extraction and gel extraction cannot be used to remove the oil from the algal biomass and sieving is a physical process of separation which cannot be used.
