The process of ensuring that a specific appliance is managing certain IP ranges is most effectively done by going to the Options menu and then selecting Appliance to assign the appropriate IP ranges. This method allows for a straightforward graphical interface where you can configure the settings directly related to the appliance's management capabilities.

When you access the Options > Appliance section, you're typically provided with features that let you specify which IP ranges the appliance should monitor or manage. This is critical for establishing network segmentation and ensuring that the appliance operates within the intended scope of the network, allowing for appropriate security measures and policies to be applied.

Utilizing this method minimizes the risk of errors that could occur if relying solely on the command-line interface (CLI), which might not offer the same level of immediate validation and feedback as the graphical interface. Consequently, option B stands out as the most effective and user-friendly approach in this scenario.
