Final answer:
Net-capital losses from before a change in control can be used against income if the business continues to operate profitably or with an expectation of profit.
Step-by-step explanation:
When shares are transferred from one group of shareholders to another resulting in a change in control of the company, certain rules apply to the treatment of losses. Specifically, option c is correct: Net-capital losses arising prior to the change in control may be used against income from the business that incurred the loss if that business is carried on at a profit or with a reasonable expectation of profit in the year in which the losses are applied. This means that if a business continues to operate after a change in control, and it is profitable or expected to be profitable, the accumulated net-capital losses from before the change can still potentially be utilized to offset taxable income.
