What is the base plan for the set of stacked cubes?

Eight stacked cubes are shown. Two cubes are side by side at the front of the image. Directly behind and adjacent to the left cube is a stack of 2 cubes. Directly behind and adjacent is a stack of 3 cubes. To the left of and adjacent to the lower cube in this last stack is a single cube.
A. 5 cubes are stacked. The bottom center of the stack is labeled front. The right side is labeled right. At the left of the stack, a cube sits on another. Both are labeled 1. The cube to the right is labeled 2. The next cube to the right is labeled 3. The cube above 3 is labeled 1.
B. 5 cubes are stacked. The bottom center of the stack is labeled front. The right side is labeled right. At the left of the stack, a cube is labeled 1. The cube to the right is labeled 3. The cube below is labeled 2. The next cube below is labeled 1. The cube to the right is labeled 1.
C. 5 cubes are stacked. The bottom center of the stack is labeled front. The right side is labeled right. At the left of the stack, a cube is labeled 1. The cube to the right is labeled 1. The cube above is labeled 1. The next cube above is labeled 1. The cube to the right is labeled 1.
D. 5 cubes are stacked. The bottom center of the stack is labeled front. The right side is labeled right. At the left of the stack, a cube is labeled 1. The cube to the right is labeled 1. The cube above is labeled 2. The next cube above is labeled 3. The cube to the right is labeled 1.

Based on the description provided, the base plan for the set of stacked cubes is option B. The cubes are labeled as follows:

- Left cube: 1
- Right cube: 3
- Cube below right cube: 2
- Cube below left cube: 1
- Cube above right cube: 1

This arrangement matches the description given in the question.
