(A)

Step-by-step explanation:

We can see that the resistors are connected in parallel so all of them have the same voltage of 100 V. We also know that


P = VI

Since resistor Y dissipates 100 W of power, we can solve for the current as


I = (P)/(V) = \frac{100\:\text{W}}{100\:\text{V}} = 1.0\:\text{A}
