As we know that magnetic field decreases with increasing distance but that is not useful in predicting the ranking here as all the loops in four cases are at same distance from center.
Therefore, direction of current will be the principle criteria to find the magnitude of magnetic field at the center.
Now, for this, we will use right hand rule. In this we curl the fingers of righ hand along the current and the thumb will give us the direction of magnetic field.
Now, let's consider arrangement D, we can see that all the loops have current in same direction and asper right hand rule, the magnetic field be pointing into the paper for all loops and will add up. Therefore, it has the largest magnitude of magnetic field at the center.
Now, we will need to consider the distance of loop from center
Keeping everything constant, the ranking will be
C < B < A < D

Two circular current-carrying loops of wire are shown in the drawing. The inner loop has a radius of R0 and carries a current I0, while the outer loop has a radius of 2R0 and carries a current of 4I0. The currents are in opposite directions. If R0 = 0.20 m and I0 = 2.3 A, determine the magnitude and direction of the net magnetic field at the center of the two loops.
