Stuck between B and C please help?!

QUESTION 10 Last time now, with d = 2.27 m. You start the block on the track at rest, somewhere to the left of x - 0. You then release the block from rest and let it slide down. What is the maximum value of x (that is, what is the closest to the origin) from which you can release the block from rest and have it leave the track at x = 0 and go into freefall? O-1.53 m O-1.14 m O-0.81 m O-1.37 m
