Part A
At the anode of the voltaic cell oxidation reaction happens.
Part B
Anode has negative (-) sign.
Part C
Electrons flow away from the anode towards the cathode.
So in a voltaic cell anode is the negative terminal where oxidation happens whereas cathode is the positive terminal where reduction happens.

QUESTION 10 Which of the following statements concerning a voltaic cell is FALSE? A voltaic cell uses an oxidation-reduction reaction to produce electrical energy. O The oxidation half reaction occurs at the cathode. O The cell consists of two half cells. O At the anode a substance will lose electrons. O The anode and the cathode are separated by a salt bridge.
During electrolysis electrons flow toward the anode oxidation occurs at the cathode a nonspontaneous reaction is forced to occur
