Answer - A
The AWS Documentation mentions the following
Parameters are new variables that you can add to your dashboards. You can use parameters in Amazon QuickSight for filtering, for allowing users to customize what data is being used in the visual, for what-if analysis, and also to drill through from one dashboard to another. After you create a parameter, you nearly always create a control for it. These controls allow your users to change the value of the parameter with intuitive UIs like drop-downs, slider bars, text boxes, and date selectors. A value set for the parameter becomes available in the context of the dashboard.
Since this is clearly mentioned in the documentation, all other options are incorrect
