How do I reset/change my security questions on my Apple Id
You can't see the link as you only get a few attempts at getting the answers correct.

  If you can't reset your security questions
  
  Contact Apple Support in either of these circumstances:
  
  
    You don't see the link to send a reset email, which means you don't have a rescue address.
    
    You see the link to send a reset email, but you don't have access to email at the rescue address.
  
  
  A temporary support PIN isn't usually required, but Apple may ask you to generate a PIN if your identity needs to be verified.
