The correct option is A Cytosol
Glycolysis or EMP pathway is the metabolic pathway, that converts glucose into pyruvate. The free energy released in this process is used to form the high-energy compounds ATP and NADPH. Glycolysis occurs in cytosol due to availability of enzymes. This pyruvate then enters into mitochondrial matrix for further process. Thus, option A is correct.
The enzymes of EMP are not located in mitochondria, lysosomes and ribosomes. Thus, other options are incorrect.
