In which of the following designs can we test the A × B interaction?
A) A and B are crossed, and n = 1.
B) A and B are crossed, and n = 2.
C) A is nested within B, and n = 1.
D) A is nested within B, and n = 2

In a crossed design, both factors A and B are applied to all levels of each other, allowing for the testing of interactions between the two factors. Having n = 2 (or more) replicates per cell (combination of levels of A and B) provides enough data to estimate the variability necessary to test for interactions statistically.
