There is no way of doing this in HTML. You will need some sort of
client-side scripting (e.g. Javascript). Use Javascript to disable the
checkboxes on page load (that way anyone with JS disabled/unavailable
can still use them). You would need probably an onclick event on the
radio button to call a function that enables the checkboxes (and one on
the other radio buttons to disable them again).
Of course you still need to validate the data properly server-side (i.e.
ignore the checkboxes unless option 5 is selected).
