See in this case flux through the loop is not changing, beacause e(e.m.f) = - *rate of chnage of flux
in this case current is constant in solenoid , so ‘ll be the magnetic field and area of the circuit is also constant hence
B*A  = flux constant . hence its rate of change  = 0
so no emf induced hence no current in the loop

Dear student 
emf induced hence no current in the loop.
Option D is correct …...........................
Good Luck
