Final answer:
John Locke's idea of Tacit Consent refers to the implied agreement to be governed, demonstrated by actions like residing in a country. The government is deemed legitimate if it has the consent of the governed and protects their rights to life, liberty, and property. People can withdraw consent and overthrow the government if it fails to protect these rights.
Step-by-step explanation:
John Locke's idea of Tacit Consent is a) the agreement to be governed that is inferred from an individual's actions, such as living in a country. In his Second Treatise of Government, Locke proposed that a legitimate government is one that has the consent of the people it governs, and that the main role of this government is to protect the natural rights of its citizens, which include life, liberty, and property. If the government fails to protect these rights, the people have the right to overthrow it and create a new system that will serve their needs.
Locke’s social contract theory also underscores the belief that the government's authority comes solely from the consent of the governed. People agree to a government to ensure the protection of their rights but retain the right to withdraw their consent if the government becomes tyrannical.
