Which of the following brings a public corporation into existence

Acts of Parliament bring a public corporation into existence. A public corporation is a legal entity that is created by the government to undertake specific commercial or non-commercial activities on behalf of the state. This entity is created through a special Act of Parliament that defines its powers, duties, and functions. The Act of Parliament gives the public corporation a legal status, allowing it to operate independently of the government and to enter into contracts, sue or be sued, and own property. Therefore, the correct answer is Acts of Parliament.
