Answer:
The curves with solid arrows show the direction of magnetic field lines.
Loop A with current flowing in it produces a magnetic flux through B as shown.
As the current increases, in response, Loop B will produce a current in the opposite direction to resist the increase in flux.
As the current in the closer parts of the loop flow in opposite directions (as shown by hollow arrowheads), they repel each other.
