 * Is there a way to say, “Plugin A depends on Plugin B or C”? In other words, either
   Plugin B or Plugin C (or both) must be activated in order to use Plugin A?

 * So I don’t think this can be linked using “OR”. These are “AND” conditions. For
   example, take a look at how this data is analyzed here: [https://github.com/WordPress/WordPress/blob/master/wp-admin/includes/plugin-install.php#L910](https://github.com/WordPress/WordPress/blob/master/wp-admin/includes/plugin-install.php#L910)
 * To achieve your goal, I would skip this condition and move the check into the
   plugin. If either of the two plugins is missing, suspend the service and display
   a warning somewhere.

 * Not with the built-in system. The “Requires Plugins” header added in WordPress
   6.5 only supports AND — every plugin listed has to be active. For an either/or
   like yours you have to roll it yourself: hook into admin_init or plugins_loaded,
   check is_plugin_active() for B and for C, and if neither is active, show an admin
   notice and stop Plugin A from running (or deactivate it). It’s a short check,
   but there’s no core syntax for OR dependencies.
