Solution

The correct options are
A A and D
C B and C
Here as the current flows in x-axis,

Magnetic field will be independent of x-value of the point,

i.e points with same value of $r = \sqrt{y^{2} + z^{2}}$
will have same field.

Points $A, D$ have $r = 1$

And points $B, C$ have $r = \sqrt{2}$

Options $A,C$ are the correct answers.
