Which among the following subjects is not included in the Ninth Schedule of the Constitution of India?

The Ninth Schedule contains a list of central and state laws (mostly related to land reforms and other socio-economic legislation) that are protected from judicial review under Article 31B. The Monopolies and Restrictive Trade Practices Act 1969, the General Insurance Business (Nationalization) Act 1972, and the Coal Mines (Taking Over of Management) Act 1973 are all included in the Ninth Schedule. The Consumer Protection Act, 2019 is a much later, unrelated consumer-rights law and is not part of the Ninth Schedule.
