Question

Arrange the layers in order from youngest to oldest:

A. 1, 2, 3, 4, 5, 6, 7, 8

B. 8, 7, 6, 5, 4, 3, 2, 1

C. 8, 7, 6, 5, 4, 3, 2, 1

D. 1, 2, 3, 4, 5, 6, 7, 8

Answer 1

The correct order of the layers from youngest to oldest is: B. 8, 7, 6, 5, 4, 3, 2, 1.

Step-by-step explanation:

The correct order of the layers from youngest to oldest is: B. 8, 7, 6, 5, 4, 3, 2, 1. This is because in the A-B-C packing sequence, layer C is displaced horizontally from layer A, and layer B is displaced vertically between A and C. As we add more layers, the sequence repeats indefinitely.
