A Python script must display the CPU model in a support tool. The developer notices that on some systems, platform.processor() returns an empty string, while platform.machine() returns the architecture. The developer needs a fallback. Which approach is most robust?

Use platform.system() and platform.version()

Use platform.processor() and fall back to platform.machine() if it returns an empty string
