After a thorough search of the provided documents, I couldn't find a direct reference to the specific CLI command for determining if static content signing is enabled in Magento. However, the typical command for checking configuration settings in Magento is bin/magento config:show <path>, where <path> is the configuration path for the setting you wish to view. Based on Magento's configuration path patterns and the options provided, the most logical choice would be B. bin/magento config:show dev/static/sign, although this cannot be confirmed without further context or documentation.
