You can attach attributes (which is a subset of "affiliated keywords"
category) to any element excepted clock, headline, inlinetask, item,
planning, node-property, section and table-row types.

So, plain lists can have attributes, but not items. There are
workarounds, though. For example, you can use an export snippet at the
beginning of the item to mark the correct answer. Hence, assuming "qcm"
is the name of your backend, you could use:

  #+attr_qcm: :type mct
  - answer a
  - @@qcm:correct@@ answer b
  - answer c

"ox-beamer.el" uses it to specify action overlays item wise. See
`org-beamer-item' for an example.
