If question 'a' is specific to A320 then the answer is C - feedback position is signalled for the Elevators (pitch) by RVDT and on the Ailerons (Roll) by LVDT. But still think its a bad question.
As for Q2 - As Ghengis has stated - answer B - however Airbus does not have FCC's (a Mr Boeing invention) they have ELAC's (Elevator Aileron Computers) SEC's (Spoiler Elevator Computers) and FAC's (Flight Augmentation Computers)
Hope this helps
