You create a parameter named Choose Region that contains values from a field named Region.
You want users to be able to use the Choose Region parameter to interact with a chart by toggling between different regions.

What should you do next?
To enable users to toggle between different regions using the Choose Region parameter, you need to create an interaction between the parameter and the data. To do this, you add a formula that equates the Region field to the Choose Region parameter on the Filters card. This allows filtering based on the parameter's value. Therefore, the correct action is to add the [Region] = [Choose Region] formula to the Filters card.

I think B is the correct answer because we created a parameter name choose regio. So we need to add it into a filter card
c-Add region to the filters card
No, answer C is wrong. Of course, you can add Region to filters card but the question was about the parameter Choose Region and how to use it as a filter to interact with a chart. If we just add Region to filters card it has nothing to do with parameter and we can use this filter without parameter at all. That is why answer C is not the case. So we already have a parameter. Next we need to create a calculated field with formula [Region] = [Choose Region]. After that we put calculated field to filters card and set it to True. After we click show parameter and use it as a filter. This is how it works. So the right answer is B.
I think the selected answer, B is correct
No, B is wrong
I did the various examples and B is the correct answer. You can either create create a calculated field or you can add the same code in the condition tab of the Filter to tie the filtering to the parameter. Hence, the answer is B.
