    Universal Containers stores user preferences in a Hierarchy Custom Setting, User_Prefs_c, with a Checkbox field, Show_Help_c.

How should the Show_Help_c preference be retrieved for the current user?

    • ABoolean show = User_Prefs__c.getValues(UserInfo.getUserId()).Show_Help__c;
    • BBoolean show = User_Prefs__c.getInstance().Show_Help__c;
    • CBoolean show = User_Prefs__c.Show_Help__c;
    • DBoolean show = User_Prefs__c.getValues().Show_Help__c;
