Consider the Graph Below,which Is a Plot of the Relative

Consider the graph below,which is a plot of the relative energies of the various conformations of 2,3-dimethylbutane,viewed through the C-2-C-3 bond.The conformations corresponding to the 120^o and 240^o are:

A) eclipsed,more stable than the conformation at 0^o
B) eclipsed,more stable than the conformation at 180^o
C) staggered,more stable than the conformation at 0^o
D) staggered,less stable than the conformation at 180^o
E) two of these choices are true
