Do the contributions allocated to the Caisse nationale de solidarité pour l’autonomie (National Solidarity Fund for Independent Living), which contribute to the funding of the benefits in question, have a direct and sufficiently relevant link with certain branches of social security listed in Article 3 of Regulation (EC) No 883/2004 and do they therefore come within the scope of that regulation solely on the ground that those benefits relate to one of the risks set out in that Article 3 and are granted without any discretionary assessment on the basis of a legally defined position?
