How can you tell if your application's Mitosis uses run or load Mitosis?

• A. It will be included in the name of your spreadsheet.
• B. It will be indicated in the file extension.
• C. It will be shown in the environment header.
• D. It cannot be determined from the name.

Answer: (C)

The key idea is that the current operational mode of Mitosis is communicated where the app surfaces its runtime status: the environment header. This area is designed to show what the system is doing right now, including which components are active and in what mode they’re operating. When Mitosis is actually running, the header will indicate a running state for it (for example, showing something like Mitosis: Running or a RUN flag). If Mitosis is merely loaded—preparing its configuration or assets without executing its logic—the header will reflect that with a loaded or loading indication.

So, to tell which mode is in use, simply glance at the environment header and read the Mitosis status there. The other options don’t reliably indicate the mode: the spreadsheet name is user-defined and doesn’t reflect runtime behavior, file extensions denote file types rather than how a component is used, and assuming it can’t be determined from the name isn’t accurate here because the header explicitly communicates the current state.
