Hi,
unfortunately I am not able to see your screenshots.
But I think you are trying to filter the second question (single response) on the first question (also single response)
This is not possible directly.
You have to create a multiple question between these two, select the desired answer options by an equation -
select answer option "C", if A was selected in Q1
select answer option "D", if A was selected in Q1
select answer option "E", if B was selected in Q1
...
Of course these two questions are hidden.
Now you set the array filter of your second question to the multiple question.
Better you see the attached example.

P.S.
There are several threads about this in the forum
