(D) circular loop carrying current $I$ behaves as a magnetic dipole. Magnetic field lines emerge from the North pole and enter the South pole. Since the loop lies in the $x-y$ plane,the magnetic field lines pass through the loop and then loop back around to form closed paths. For every magnetic field line that passes through the $x-y$ plane in one direction (e.g.,upwards),an equal number of field lines must pass back through the $x-y$ plane in the opposite direction (e.g.,downwards) to complete the closed loop. Therefore,the net magnetic flux through the entire $x-y$ plane is zero.

$A$ circular loop of radius $R$ carrying current $I$ lies in the $x-y$ plane with its centre at the origin. The total magnetic flux through the $x-y$ plane is:
