Answer
They can lead to inflexible and error-prone code.
Bad hierarchies, like ones with too many levels or irrelevant classes, make code difficult to understand and maintain. They can also cause problems with encapsulation and increase coupling. For instance, if a 'Product' class has subclasses like 'PerishableProduct' and 'LuxuryProduct', but both need methods unrelated to 'Product', it may indicate a design issue.
