B) Rare
C) Valuable and rare
D) ​Not valuable but rare

According to the VRIO framework, a resource must be both valuable and rare to be a source of temporary competitive advantage. If a resource is valuable but not rare, it can still be imitated by competitors, and if it is rare but not valuable, it may not contribute to competitive advantage. The combination of rarity and value creates a unique and valuable advantage for the company, which competitors cannot easily imitate.
