In frame C, the magnetic field at the center of the frame will not be zero.

Explanation:

As per the given figures, only figure C will not have zero magnetic fields at the center because of the flow of the current in the same direction with uniform magnitude along with the approaching and outgoing current.

The options (A) and (B) are incorrect because the current line flows through the center which implies that the perpendicular distance from the center would be zero due to approaching and outgoing currents through the center.

The last option i.e. option D is wrong because the current approaching and the current outgoing would be equal because of the magnetic field and thus, it will be zero.

Hence, option C is the correct answer.
