The induced emf in a coil rotating in a uniform magnetic field is maximum when the plane of the coil is
Answer: (D) parallel to the field
Concept. $\varepsilon = NBA\omega\sin\omega t$, largest when the flux is zero but changing fastest.
Step 1. Orientation. Zero flux means the field lies in the plane of the coil, i.e. the plane is parallel to the field.
Answer. Parallel to the field (Option D).
