A resistor and a capacitor are connected in series to an ideal battery of constant terminal voltage. When this system reaches its steady-state, the voltage across the resistor is
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 greater than zero.
D) zero.

In steady-state, the capacitor is fully charged and acts as an open circuit, so no current flows through the resistor, resulting in zero voltage across it.
