Final answer:
Henry can run his music collection management software on a virtualized instance of the original operating system to overcome compatibility issues.
Step-by-step explanation:
If Henry has developed a software application for managing his music collection that needs to run on an incompatible operating system, the most appropriate action he can take is to run the software on a virtualized instance of the original operating system (Option B). This method involves using virtualization software to create a simulated environment where the original operating system can run inside the existing one, thereby allowing the application to function as intended. Upgrading the current operating system (Option C) might not be helpful if the software is not made to operate on it, and reconfiguring the software by rewriting the code (Option A) might be very time-consuming and impractical. Running the application as is on the new operating system would not be possible if the systems are fundamentally incompatible (Option D).
