Which of the following is NOT a requirement for a corporation to exist under the Revised Corporation Code?

The choice indicating the necessity of establishing physical office space is not a requirement for a corporation's existence under the Revised Corporation Code. The Revised Corporation Code primarily focuses on the legal and procedural aspects of corporate formation and governance. This includes requirements such as the proper filing of registration documents, which ensures that a corporation is officially recognized by the state, as well as the need to have at least one director to oversee corporate operations.

Additionally, corporations must be formed in compliance with the guidelines outlined in the corporation code, ensuring that all legal stipulations regarding their formation and operation are adhered to. However, the code does not mandate that a corporation must have a physical office location to be valid or operational. This allows companies to operate in a more flexible manner, especially in the era of remote work and digital businesses, where a physical presence isn't always necessary for legal existence.
