In the context of Redelmeier's algorithm for enumerating fixed polyominoes, what issue or limitation might occur during the generation process?
A) The algorithm might produce polyominoes with disconnected interiors.
B) The algorithm could lead to duplicate polyominoes in the enumeration.
C) The algorithm may get stuck, preventing further tiles from being added to the current polyomino.
D) The algorithm might skip certain valid polyominoes in the enumeration.
