From oldest to youngest the layers of rock are: 4,5,2,B,6,1,3,A
The reason 4 and 5 are listed as the oldest is because they are on the bottom. 2 is next because it cut through 4 and 5 but the B cut through 4, 5 and 2 so that make it younger than 4, 5 and 2. Next is number 6 because it is above the layers listed before, then it is number 1 because it is above all the layers listened before. Then is number 3 because it cuts through every layer answered before. The lastly is conformity A because it is conforming everything and not just some layers.
You're right on, with the exception of "A." It separates the sedimentary layers above it from the tilted ones below it.
