Answer:
B. Charles Pinckney
Step-by-step explanation:
Charles Pinckney was an American politician and planter born on the 26th of October, 1757 in Charleston (formerly know as Charles Town), South Carolina and died on the 29th of October, 1824 in Charleston, South Carolina. He was the 37th governor of South Carolina and signed the Constitution of the United States of America.
Charles Pinckney was known as a strong and harsh critic of the weak, inefficient, and inadequate Articles of Confederation of the United States of America.
Hence, the South Carolinian who was a harsh critic of the weak federal government is Charles Pinckney and as such was an advocate for a strong federal government.
