How do i require a signer to select just one check box?

I use Adobe Acrobat Sign to send out new hire onboarding forms such as the I-9, W-4 form, etc. I know how to make a field "Required", but how do i set it up to where just ONE of the mulitple choice fields are required?  For example, they have to select just ONE box for Citizen, Non-Citizen, or Lawful Permanent Resident, etc.  Another example is on the W-4's they have to select if they are Single, Married, etc.  They only need to select one option. Any advice is appreciated!

Thank you.
