Two circular loops `P` and `Q` are concentric and coplanar as shown in figure. The loop `Q` is smaller than. `P`. If the current `I_1` flowing `i` loop `P` is decreasing with time, then the curren `I_2` in the loop `Q`
A. Clockwise
B. zero
C. counter clockwise
D. in a direction that depends on the ratio of the loop radii
