Few First World War cruisers were worth retaining

Which First World War Royal Navy cruisers were worth retaining for the Second World War?

Possibly the Active class, but keeping more C-class cruisers would have been more useful.

Sheer hull count provides the limited case for preserving very old cruisers. The Active class might still fill secondary duties when wartime demand makes every serviceable hull valuable. That does not mean all First World War cruisers offer equal utility. Retaining more C-class ships would provide a stronger combination of size, capability, and modernization potential than keeping most earlier designs.
