Required Group of Radio Buttons
Apply a “title” attribute to the <input> field. If a form field has a title attribute but no <label>, screen readers will treat the title as a label.
This approach is generally less reliable as some screen readers and assistive technologies do not interpret the title attribute as a replacement for the label element.
The information of the title attribute is shown to visual users as a tool tip when hovering over the form field with the mouse.

Markup
Use the “aria-required” attribute in combination with the “radiogroup role” in the fieldset tag.
