C. to protect individual freedoms from abusive governmental power
Explanation:
The initial draft of the constitution did not necessarily mentioned the things that the government can't do to the citizens.
The Bill of rights contained the first 10 amendments in United States constitutions. These amendments specifically designed to protect the rights of citizens and cannot be taken away by the government in any way or form.
One example, the first amendments within the bill of rights gave the citizens with the freedom to speech. This enables the citizens to openly criticize the government on public platforms without having to fear that they're going to get jailed.
