Hi @Shamiqbal ,
If the question is a multiple-choice, you may refer to the following configuration to achieve your needs.
I assume that this question has three options. First, use the json() function to format the response to an array.
Considering that the user will not select all options, so we need to check the length of the array and get the element by the existing index. Hope that makes sense.
Image reference:

Expression reference:
if(greaterOrEquals(length(outputs('Options')),1),outputs('Options')[0],null)
if(greaterOrEquals(length(outputs('Options')),2),outputs('Options')[1],null)
if(greaterOrEquals(length(outputs('Options')),3),outputs('Options')[2],null)
Please take a try and feel free to let us know if you have any questions.
Best Regards,
