Good Morning!
Article 5 of the Constitution of the United States of America guarantees the possibility of including amendments to the original document. Thus, if two-thirds of the members of both legislative chambers deem it necessary, or even if the legislature of two-thirds of the States deems it necessary, a convention shall be convened for the purpose of proposition and amendment.
Letter b) The Constitution would be a living, breathing document that would change with the times.
Hugs!
