Two identical permanent bar magnets, Magnet 1 and Magnet 2, are arranged in a horizontal plane on a coordinate grid as shown in the diagram below.

Magnet 1 lies along the $y$-axis with its North (N) pole facing the origin $P$ at a distance $d$. Magnet 2 lies along the $x$-axis with its North (N) pole facing the origin $P$ at the same distance $d$.

Four arrows, A, B, C, and D, represent possible directions for the resultant magnetic field vector at the origin $P$.

Which arrow correctly represents the direction of the resultant magnetic field at the origin $P$?
