Final Answer:
Space being used that has no alternative use does not have an opportunity cost. Option B is correct.
Step-by-step explanation:
Opportunity cost refers to the value of the next best alternative forgone when a decision is made. In the case of a.), where space could be used for another purpose, the opportunity cost exists because the space could have been utilized differently, potentially offering benefits or returns. However, in b.), when space has no alternative use, there's no foregone benefit or value associated with that specific space utilization since there are no alternative options available.
