The figure shows certain wire segments joined together to form a coplanar loop. The loop is placed in a perpendicular magnetic field in the direction going into the plane of the figure. The magnitude of the field increases with time. I1 and I2 are the currents in the segments ab and cd. Then,

• A. I1 u003e I2
• B. I1 u003c I2
• C. I1 is in the direction ba and I2 is in the direction cd
• D. I1 is in the direction ab and I2 is in the direction dc
