The quote that best explains the differences between each congressional chamber's approach to the legislative process is:
"Each House may determine the Rules of its Proceedings."
This quote highlights the autonomy of each chamber (the House of Representatives and the Senate) to establish its own rules and procedures for how it conducts business, which reflects the differences in their legislative processes. The House is generally more structured and has stricter rules compared to the Senate, which allows for more open debate and has fewer constraints on legislative procedures.
