Correct option is A)

Reduction at cathode (negative electrode) :
ions from the solution gets attracted by the negative electrode (cathode) which have excess electrons. These  ions take the electrons from the cathode and thus gets reduced as atoms. As the two copper plates are moved further, more and more  ions are reduced at the cathode and hence larger amount of copper deposits on the plate connected plates to the negative electrode (cathode).
