the answers are correct. Indicates whether all the ribbon command bars on the current page are refreshed. If you specify false, only the page-level ribbon command bar is refreshed. If you do not specify this parameter, by default false is passed. https://learn.microsoft.com/en-us/power-apps/developer/model-driven-apps/clientapi/reference/formcontext-ui/refreshribbon#parameter

Example of using B or D. - A Business rule sets a value in a column - Button visibility rule depend on the value in the previous column - A JavaScript Web Resource is added to the on change event of the same column, so it gets triggered and executes either formContext.ui.refreshRibbon(refreshAll) or formContext.ui.refreshRibbon(), which refresh all ribbon command bars in the current page or only the page-level ribbon command bar, respectively (Both would work in this case) . This would ensure that the button is either displayed or not depending on the business rule.

D is incorrect as no parameter is specified in formContext.ui.refreshRibbon(??); If you do not specify this parameter, by default false is passed.

I think B and C. D will not refresh the button because it is was added to the app ribbon, so must pass RefreshAll. C because after refresh OnLoad event is triggered: https://docs.microsoft.com/en-us/power-apps/developer/model-driven-apps/clientapi/reference/formcontext-data/refresh
