You can accept a SVFR clearance in a Class A CTR only, not in a Class A CTA, airway or TMA. The question doesn't mention CTR. As most Class A is not a CTR, I would take it to be that it's not permitted with regards to the question.
Class A CTRs will not exist by the end of the year, so there will definitely be no SVFR in any Class A soon.
