unable to understand the problems in choice B]
Why A] a better choice?
Hello
himanshu0123,
We hope this finds you well.
To answer your query, Option A alters the meaning of the sentence through the "making provision for the removal of..."; the use of the "comma + present participle ("verb+ing" - "making" in this sentence)" construction illogically implies that the Act of Congress was approved April 24, 1800, and
as a result it made provision for the removal of the government of the United States to the new federal city; the intended meaning is that the Act of Congress was approved April 24, 1800, and
as a separate action it made provision for the removal of the government of the United States to the new federal city; remember, the introduction of present participle ("verb+ing"- “making” in this case) after comma generally leads to a cause-effect relationship.
