D) decreases.

Quizplus · Accepted Answer

When resistors are added in parallel, the overall resistance of the circuit decreases, leading to an increase in the total current drawn from the source. Since power (P) is calculated as P = V * I (where V is the constant voltage and I is the current), an increase in current results in an increase in the power supplied by the source.
