Shown Below Is a Galvanic Cell with Anode Compartment B $\rarr$

Shown below is a galvanic cell with anode compartment b containing anode a and cathode compartment d containing cathode c.Electrons flow through wire f,ions flow through salt bridge e,and the cell potential is read using voltmeter g.
This galvanic cell uses the reaction: Cu(s) + 2 Ag⁺(aq) $\rarr$ 2 Ag(s) + Cu²⁺(aq) .
-The initial concentrations of Ag⁺(aq) and Cu²⁺(aq) are both 1.0 M.What will happen to the cell voltage if 1.0 M Cu(NO₃) ₂ is added to the compartment containing the 1.0 M Cu²⁺(aq) ? The cell voltage will

A) decrease.
B) increase.
C) remain the same.
D) can't tell from the information given
