Answer:
D. Resource Immobility
Explanation:
Resource immobility is the concept that if a resource is easy to obtain by competitors because the cost of developing, acquiring or using that resource is relatively low, then that resource cannot provide competitive advantage.
Sometimes, resources are not free or able to move between markets. This may lead to the resources not being used as efficiently as possible. Due to this immobility, companies cannot replicate rivals’ resources and implement the same strategies.
