Table which contains checkboxes and radio buttons – labels issue

Table, which enables users to configure items within. User can select "active" items (checkboxes) and among them he/she needs to select just one "best one" item (radio button).

I created 5 possible versions, how this could be displayed:

    1. Both checkbox and radio button have label (no matter what)
    1. Checkbox has label, but label for inactive radio button is greyed out (to indicate that this item cant be selected as "the best one")
    1. Checkbox has label just when it's marked as active, radio button has label just when its selected as the "best one"
    1. Checkbox has label just when it's marked as active, radio button has label when it may be selected as the best one
    1. Both checkbox and radio button don't have label (IMO there is a big chance that it will be confused with bulk action checkbox - undesirable effect!)

Additional concern (if label is applied):

  • A. Should label "answer" the top-cell statement, and label should always say the same?

  • B. Should label repeat top-cell statement?

  • C. Should label "answer" the top-cell statement, and label should say different thing for checked ("Yes"), and different for unchecked item ("No").
