html in form label

I am putting together a form

it includes a radio list, in the radio list we have chemical formula such as C2O. In this, the 2 needs to be subscript ₂

In addition we have mention of species names for plants. The latin species name needs to be in italics. When I add the code to the radio list the html is output on the page.

Is there a way to include html in the label visible on screen.

I have tried using pipes to include different code for label and data, but that does not seem to be working for radio lists – https://contactform7.com/selectable-recipient-with-pipes/

Many thanks
