There Is No Current in the Circuit Shown in the Figure

There is no current in the circuit shown in the figure below until the switch is closed.The current through the 20-Ω resistor the instant after the switch is closed is either [1] 15 A or [2] 5.0 A,and the current through the 20-Ω resistor after the switch has been closed a long time is either [3] 5.0 A or [4] 15 A.Which combination of the above choices is correct?

A) [1] and [3]
B) [1] and [4]
C) [2] and [3]
D) [2] and [4]
E) None of these
