Answer
A is true but R is false.
Explanation — The reaction at anode involves oxidation of anions as they lose electrons to become neutral. Hence the assertion (A) is true.
Electrons are donated or lost at the anode. However, gain of electrons takes place at cathode, where cations are reduced. Hence the reason (R) is false.
