A Square Conducting Loop Is Situated Such That It Is

A square conducting loop is situated such that it is vertical,in the x-z plane.The earth's gravitational field points downward (in the -z direction) .The loop is dropped,and maintains its orientation in the x-z plane.A magnetic field pointing in the +y direction exists and is uniform with respect to time,but varies as a function of z: B(z) = B_o(10 m - z) .The loop is dropped and allowed to fall under the influence of gravitation.You observe the loop from the +y direction.Which of the following occurs?

A) The situation is unclear because we do not know the initial conditions.
B) There is a clockwise induced current.
C) There is a counter-clockwise induced current.
D) There is no induced current.
