I think the correct answer from the choices listed above is option 1. The energy conversion that must occur in an electrolytic cell is the conversion from electrical energy to chemical energy. The reaction must be forced by applying an external electric current thus needing a supply of electric current.

The energy conversion that occurs in an operating electrolytic cell is from electrical energy to chemical energy. An external electric current drives non-spontaneous reactions to take place. Therefore, the correct answer is option A.
