You could write JavaScript to hide all the choices, then randomly show 10 choices from each subgroup based upon your criteria (i.e., if they see A_1 they can't see B_1, C_1 or D_1).

Hi TomG,
Thank you for your assistance!
Unfortunately, I have a very limited knowledge on Javascript and would not be able to write such a thing. I tried to found similar codes here in this community according to your answer, but no success so far. I will keep trying though.
Thank you for your time

If the order of appearance is not important. You can have the question at the top and then put each of the exclusive choices in a separate question on the same page, without any question text, just the choices. You can then randomize the choices in each question for only one to appear.
There will be some white space, but to your participants it will appear like one question.

Thank you for your help. The numbers in my project represent a unique theme (I have 40 themes in total), and the letters are different versions of each theme. I want participants to see 10 choices from each subset however the themes cannot repeat themselves, i.e. they cannot see multiple versions of the same theme. I tried to do your suggestion, however, I still get participants seeing two or more versions of the same theme (e.g. A_1 and B_1). I want something like:
From subset A: A_1 to A_10
From subset B: B_11 to B_20
From subset C: C_21 to D_30
From subset D_31 to D_40
I was able to use embedded data and choice display logic to show 10 choices from each subset. However, I have no idea how to guarantee that all the themes are presented.
Thank you for your time.
Best,
Angelica
