If a Product Option is unavailable due to an Option Constraint, how will this appear to the user?

If a Product Option is unavailable due to an Option Constraint, it will appear to the user by greying out the checkbox or radio button for that specific Product Option. This visual cue indicates to the user that the option is currently unavailable for selection. This helps maintain transparency in the configuration process and assists users in understanding why certain options are not selectable at that moment.

Options B, C, and D are incorrect because in Salesforce CPQ, the standard behavior is to grey out the checkbox or radio button for the unavailable Product Option rather than hiding it, moving it to the bottom of the Feature, or moving it to a separate Feature named Unavailable Options.
