Figure shows a part of an electric circuit. The potentials at points $a$ , $b$ , and $c$ are $30 \, \text{V}$ , $12 \, \text{V}$ , and $2 \, \text{V}$ respectively. The current through the $20 \, \Omega$ resistor will be:

Circuit with point a connected through a 10 ohm resistor to a junction, which splits into an upper 20 ohm branch ending at b and a lower 30 ohm branch ending at c, with current directions shown left to right.

A
$1.0 \, \text{A}$
B
$0.2 \, \text{A}$
C
$0.4 \, \text{A}$
D
