I can not reset the security questions

The reset link will only show if you have a rescue email address (which is not the same thing as an alternate email address) set up on your account. If you aren't getting the link then you don't have one, and you won't be able to add one until you can answer 2 of your questions - you will need to contact iTunes Support / Apple to get the questions reset (we are fellow users here on these forums).

Contacting Apple about account security : http://support.apple.com/kb/HT5699

When they've been reset you can then use the steps half-way down this page to add a rescue email address for potential future use : http://support.apple.com/kb/HT5312

If you aren't getting the link then it's not a rescue email address, it will be an alternate/secondary email address. You will need to contact Apple to get the questions reset.
