A magnetic flux through a circuit increases linearly with time, then the absolute value of the induced e.m.f
A) increases because the flux is increasing
B) decreases because according to Lenz's law it opposes the original increase of the flux
C) stays the same at all times

That's a strange School Subject.
It's physics
The induced emf in a coil is equal to the negative of the rate of change of magnetic flux ...
So, if the flux increases, the emf decreases, but the absolute value increases.
So, if the flux increases, the emf decreases, but the absolute value increases.
