Given below is the plot of a potential energy function U(x) for a system, in which a particle is in one dimensional motion, while a conservative force F(x) acts on it. Suppose tha `E_("mech")`= 8 J, the incorrect statement for this system is :


A. at `x` > `x_4`, K.E. is constant throughout the region.
B. at `x` < `x_1` K.E. is smallest and the particle is moving at the slowest speed.
C. at `x` = `x_2` , K.E is greatest and the particle is moving at the fastest speed.
D. at `x` = `x_3`, K.E. = 4 J
