In a region with magnetic declination of $2^{\circ}E$, the magnetic Fore bearing (FB) of a line $AB$ was measured as $N79^{\circ}50'E$. There was local attraction at $A$. To determine the correct magnetic bearing of the line, a point $O$ was selected at which there was no local ... true $FB$ of line $AB?$ $N81^{\circ}50'E$ $N82^{\circ}10'E$ $N84^{\circ}10'E$ $N77^{\circ}50'E$
