Correct option is d.
Referring to the figure of the point O with the arrows, the right hand rule (according to which if your thumb point in the direction of current, then the direction along which the fingers curl will give the direction of magnetic field) says that direction of the magnetic field at O due to the left wire (cross) will lie between (c) and (d), while, the direction of magnetic field at O due to the right wire (dot) will lie between (a) and (d). So, taking the resultant of this two field will give the direction of the net magnetic field at O along (d).
