You can use the right hand grip rule to determine. In this case, direction of current is indicated by your right thumb. Hence magnetic field is pointing into the plane for options A and C for the horizontal wire. Similarly when you analyse the vertical wire, you notice that by the right hand grip rule, magnetic field is pointing into the plane for C and not A. Hence the strongest magnetic field pointing into the plane is option C.
