The Network Shown Is Assembled with Uncharged Capacitors X ,Y,and

The network shown is assembled with uncharged capacitors X ,Y,and Z,with C_X = 4.0 μF,C_Y = 6.0 μF,and C_Z = 5.0 μF.The switches S₁ and S₂ are initially open,and a potential difference V_ab = 120 V is applied between points a and b.After the network is assembled,switch S₁ is then closed,but switch S₂ is kept open.What is the final potential difference across capacitor X?

A) 120 V
B) 82 V
C) 75 V
D) 67 V
E) 60 V
