Magnetic flux = BA cos
Since, magnetic field B is parallel to crossection area A,
is 0
Therfore magnetic flux = BA
Since area A is decreasing as rod comes closer to the bulb the magnetic flux also decreases.
Since the direction of magnetic field is out of the page using right hand thumb rule we can deduce that the induced current is counter clockwise
Therefore the answer is option c

A circular loop of flexible iron wire has an initial
circumference of 165.0cm, but its circumference is decreasing at a
constant rate of 12.0cm/s due to a tangential pull on the wire. The
loop is in a constant, uniform magnetic field oriented
perpendicular to the plane of the loop of magnitude
0.500T.
