The magnetic flux `(phi)` linked with a coil varies with time (t) as `phi=at^(n)`, where a and n are constants. The induced emf

The magnetic flux `(phi)` linked with a coil varies with time (t) as `phi=at^(n)`, where a and n are constants. The induced emf in the coil is e. Which of the following are correct?
A. if `0ltnlt1,e=0`
B. if `0ltnlt1,ene0` and |e| decreases with time
C. if n = 1, e is constant
D. if `ngt1,|e|` increases with time
