Graph of Induced EMF Over Time

APPH12-ENGYQX

At time $t=0$, a loop of wire begins being pushed at a constant speed into a region where a uniform magnetic field exists. The loop's area is perpendicular to the direction of the field. At $t=1$ second, the loop completes the process of entering the field so that it is now entirely within the field, and now the loop continues to be pushed at the same constant speed through the uniform field.

Which one of the following is the correct graph of the magnitude of induced emf versus time for this loop, from $t=0$ to 2 seconds?

A
B
C
