Answer:
Explanation:
I don't know what Answer A really is. Usually there is a numbered section preceding the clause. The clause does not stand by itself -- or nothing I've seen does that.
Article 4 section 5 clause 3: This part of the constitution tells how the constitution may be amended. To amend or change anything about the constitution requires a procedure. This then is the procedure.
I think the answer you want is B. The wording is "To Constitute Tribunals inferior to the the Supreme Court." This whole section 8 Article I has to do with the powers given to congress. Clause 9 is just one of these powers.
