You could make the choices of a multiple choice question into table rows and then use JS to move the radio buttons into the desired cell. Here's the demo for the code below:
Question HTML:
        
        Please make your choice
Choices (Entered through edit multiple):

Choice	Investment	Remaining Balance	Number of Shares	Your Decision

Choice 1

$ 2

$ 0

10

Choice 2

$ 1.5

$ 0.5

9

Question JS:
Qualtrics.SurveyEngine.addOnReady(function () {
let all_inputs = this.getQuestionContainer().querySelector("ul").querySelectorAll(".q-radio");
let all_rows = this.getQuestionContainer().querySelector("ul").querySelectorAll("tr");
all_inputs(0].hide();
for (i = 1; i < all_inputs.length; i++) {
        all_rowsri].lastElementChild.insert(all_inputs_i]);
        all_inputsti].style.float = "none";
        all_inputsti].style.verticalAlign = "middle";
}
});

ahmedA Thank you very much for your help Your demo looks fantastic!
I managed your code to have a proper table, but somehow I could move the radio buttons into the desired cell.
Although I tried to implement your code as you suggested.
Where is my mistake?
And looks the table also the same for the mobile view as for the computer view?
Thank you very much and all the best!

It appears that you have inserted the code properly, so the error must lie elsewhere. Can you check if you are getting any errors in the console (If you haven't used the console before, you'll find resources related to your browser online).
Are you using a multiple choice single answer question with horizontal choices? If not, then you'll need to switch to it. It could also be related to the theme, I use the boxed question theme available in the old look and feel editor.
See if any of these solve your problem.
