24. What does U-shaped learning in language acquisition represent? (A) The child consistently improved their language skills over time. For example, they started by saying "went" and continued using it correctly without making errors. (B) The child initially acquired the correct form but then stopped using it. For example, they began by saying “went” and later stopped using it without any apparent reason. (C) The child began with a silent period and then moved on to using an overgeneralized form. For example, they initially said nothing and later started saying “goed” instead of “went”. (D) The child initially spoke correctly, for example, saying "went," then made errors like "goed", before eventually returning to "went" as they learned exceptions.
