[单选题]
04.42: A solenoid is o5 ueay8ww.hx *kw;8 .u; pg k*od0idfyriented end-on so that its opening is perpendicular to the circuit containing the two light bulbs as drawn in figure C1. For figures C2 and C3, a shorting wire of negligible resistance is added as shown. Assume that the magnetic field from tod;ikkgy8u d; 0p *w.fhe solenoid, shown coming out of the plane of the page, decreases uniformly in time at the same rate for each circuit. Rank the circuits for the brightness of the bulb labeled R1 from brightest to dimmest.



A. C1 > C3 > C2
B. C1 > C2 = C3
C. C2 > C3 > C1
D. C3 > C1 > C2
E. C3 = C2 = C1
