(D) Let the initial magnetic field be $B_1 = 1 \, T$ and the perpendicular magnetic field be $B_2 = \sqrt{3} \, T$.When a magnetic needle is placed in two mutually perpendicular magnetic fields,it aligns itself along the direction of the resultant magnetic field.The angle $\theta$ that the needle makes with the direction of $B_1$ is given by the tangent law:$\tan \theta = \frac{B_2}{B_1}$Substituting the given values:$\tan \theta = \frac{\sqrt{3}}{1} = \sqrt{3}$Since $\tan 60^o = \sqrt{3}$,we have:$\theta = 60^o$
