Final answer:
The gain on the sale should be allocated based on the proportion of ownership.
Step-by-step explanation:
The correct statement is 3) The gain on the sale should be allocated based on the proportion of ownership.
When a company sells an asset and records a gain, it needs to allocate that gain among its shareholders. In this case, Major owns 80% of Minor's common shares, so the gain should be allocated based on this ownership percentage.
For example, if the gain on the sale is $30,000, 80% of that amount ($24,000) would be allocated to Major and 20% of that amount ($6,000) would be allocated to the noncontrolling interest.
