If you mean for this change to happen dynamically, after the user-agent has rendered the page and the viewer is clicking around, the monks above have the solutions for you.

When I first read your question, though, I assumed you were designing a multi-page form, or perhaps a "Sorry, but you didn't fill out X and Y in the form, please fill it out and submit it again" page. If that is so, what you need is some logic to check the incoming checked/unchecked status of MITRA, SPACE, and MEME, and execute "-disabled => [ '2 Fastest' ]," only if one of them was checked.
