A 9-V battery is hooked up to two resistors in series using wires of negligible resistance. One has a resistance of $5 \Omega$, and the other has a resistance of $10 \Omega$. Several locations along the circuit are marked with letters, as shown in the figure. Which statements about this circuit are true? (There could be more than one correct choice.)

A) The current is exactly the same at points A, B, C, and D.
B) The potential at $B$ is equal to the potential at $C$.
C) The current at $A$ is greater than the current at $B$, which is equal to the current at $C$, which is greater than the current at D.
D) The potential at $D$ is equal to the potential at $C$.
E) The current at $\mathrm { A }$ is greater than the current at $\mathrm { B }$, which is greater than the current at $\mathrm { C }$, which is greater than the current at $D$.
