Centering answer options (or aligning answer options of groups to the left)

Hi their,
we have a question where some of the answer options should automatically exclude certain other answer options. This works perfectly fine using groups within the answer options.
Unfortunately, the answer options within the groups are aligned to the center. Is it somehow possible to align the group options to the left, or to also center the answers that are not part of groups? Somehow, using the align center / align left doesn't work in the Rich Content Editor (i.e., html).
Any suggestions? Here's a picture as example:
