replace with option button in word

[dgrosen]

Hi: I need help creating a macro to format a word document.
I have a multiple choice quiz with 100+ questions in the following format:

1- which is the capital of france ?
a- paris
b- madrid
c- new york
d- rome

2- which is the capital of spain ?
a- paris
b- madrid
c- new york
d- rome

I would like a macro to replace the options with option buttons so the student can interactively select the correct answer.
Thanks
