How the rule works
One figure lies inside another, and the inner one follows a rule of its own: it changes shape row by row, or is distributed as three values over rows and columns. The outer one may follow another rule at the same time, or stand still.
The task therefore has two layers, and they must be read separately. Anyone who sees the cell as a single figure finds no rule at all. Start with the outer one, then the inner one, and check the options against both.
