The correct option is C CF0 and CF1
ATP synthase is an enzyme located in the chloroplast and helps in the synthesis of ATP. The chloroplast ATP synthase has two parts: CF0 located in the thylakoid membrane and CF1 that protrudes on the outer surface of the thylakoid membrane facing the stroma. The CF0 forms a transmembrane channel for the movement of protons due to which energy is released and that causes conformational changes in the CF1 of the enzyme. Utilising this energy, ATP is synthesised from ADP by the enzyme ATP synthase.
