Final answer:
Options A, B, C, and D can lead to a loss of control except for option D, where the subsidiary issues a stock dividend or a stock split.
Step-by-step explanation:
In the context of parent companies losing control over subsidiaries and discontinuing future consolidation, all the options A, B, C, and D can potentially lead to a loss of control except option D, where the subsidiary issues a stock dividend or a stock split.
When a parent company sells some of its interest in a subsidiary (option A), it might result in a decrease in control. Similarly, when a subsidiary issues additional common stock (option B), it dilutes the parent company's ownership and control. If a subsidiary comes under the control of the government or other regulators (option C), the parent company might lose control or face restrictions on consolidation.
