E

This one's a little bit tricky because I didn't feel safe crossing the road, but you know at least two of the three units pretty well. Based on what you have seen, you should be able to look at A, and tell that this unit is not A. This unit has a very different color, and you don't see the stark white veins that you saw in A. While, if you look at stop C, you should see that there are some similarities. While this one appears less red, keep in mind that it is wet (while stop C is not) and in the shade. But you should see them breaking in a similar manner.
