Which of the following can be classified as entities for reporting under discontinued operations?

Discontinued operations refer to components of an entity that have been disposed of or are classified as held for sale and represent a strategic shift that has a major effect on an entity's operations and financial results. The correct classification for reporting under discontinued operations includes components, groups of components, businesses, and nonprofit activities. This broad definition allows for a comprehensive understanding of what constitutes discontinued operations, ensuring that all relevant activities that have ceased operations or are being sold off are properly accounted for in financial statements.

Components of an entity can include various segments, divisions, or operating units, and grouping them can also capture larger transactions where multiple related parts are discontinued together. Furthermore, recognizing nonprofit activities as potential candidates for discontinued operations acknowledges that such entities also engage in business-like activities that can be terminated or sold.

By including all these types of entities, the standard promotes transparency and allows investors and stakeholders to gain a clearer picture of an organization's ongoing operations versus those that have been discontinued, improving the overall utility of financial reporting. This is why the classification of components, groups of components, businesses, and nonprofit activities under discontinued operations is the most accurate and inclusive choice.
