Which V-speed represents maximum flap extended speed?

Explanation:
The speed limit when flaps are extended is V_FE. Flaps are a high-lift device; when you deploy them, you gain lift but also drag and different wing loads. To protect the flap mechanism and maintain safe handling, you must not exceed the flap-extended speed. V_FE is the specified maximum you should not pass with the flaps out. The other terms refer to different configurations: VLE (or V_LE) is the speed with landing gear extended, and V_S0 is the stall speed in the landing configuration. Neither of those is the flap-extended speed, so they don’t apply to this question.
