As more resistors are added in parallel across a constant voltage source, the power supplied by the source

a. decreases.

b. does not change.

c. increases.

As more resistors are added in parallel across a constant voltage source, there are more paths for current to take. So more current dribbles out of the source, and the total current supplied by the source increases.

The power supplied by the battery is (voltage) x (current). So if the voltage is constant and the current increases, the power being supplied must also increase.
