A)greater than the battery's terminal voltage.
B)equal to the battery's terminal voltage.
C)less than the battery's terminal voltage, but not zero.
D)zero.

At the moment contact is made, the inductor initially opposes any change in current, so the current is zero. Therefore, the voltage across the resistor, which depends on current, is also zero.
