According to Faraday's second law,
emf =−

dϕ

dt

, i.e. rate of change of flux and flux, ϕ=B.A=BA‌cos‌θ
where, B is magnetic field.
A is area of cross-section.
∴ϕ=BA‌cos‌0°=BA⇒ϕmax=BA
∴ Induced emf is not zero.
Therefore, A is false and R is true.
When plane of coil is perpendicular to the magnetic field, then, θ=0°.
