A)0.1.
B)0.001.
C)0.01.
D)0.0001.

The small unit would be one-tenth of one side of the large cube, i.e., 10 units ÷ 10 = 1 unit. Therefore, the volume of the small unit would be (1 unit × 1 unit × 1 unit) = 1 cubic unit. Since the large cube represents one, it has a volume of (10 units × 10 units × 10 units) = 1000 cubic units. So, the small unit represents (1/1000) of one, which is 0.001. Therefore, the correct choice is B, i.e., the small unit represents 0.001.
