Detailed Solution

At 1 s, inward magnetic field is increasing. Hence, induced current will produce outward magnetic field. Therefore, induced current is anticlockwise.At 5 s, flux is constant. Hence, induced current is zero. At 9 s, outward magnetic field is increasing. Hence, induced current will produce inward magnetic field. Or the induced current is clockwise.
