Answer:
there is no opportunity cost
Step-by-step explanation:
Opportunity cost occurs when the transferring division has to forego its supply to the external market by supplying internally due to capacity limitation.
Since the Orange division has enough capacity to produce 10,000 units, it has excess capacity to meet the 2,000 units required by the Colter division without affecting is current supply of 8,000 units to the external market.
Thus there is no opportunity cost under the current circumstances.
