Answer
(a) (b) (c) (d)
Work Step by Step
Flux = $BAcos\theta$
So, flux is determined by B,A and $\theta$ and also the direction.
Hence, it depends on (a) area of the coil, (b) strength of the magnetic field,
(c) orientation of the loop with respect to the field direction and (d) direction of the field relative to the loop.
