The correct answer is: A. Companies Act 2006.
The Companies Act 2006 is an Act of the Parliament of the United Kingdom that consolidated the previous Companies Acts 1862 to 2006. It is the primary legislation governing companies in the United Kingdom. The Act was passed on 8 November 2006 and came into force on 1 October 2006.
The Act sets out the requirements for forming a company, the rights and duties of shareholders and directors, and the procedures for winding up a company. It also contains provisions relating to financial reporting, auditing, and takeovers.
The Companies Act 2006 is a complex piece of legislation, and it is important for companies to comply with its requirements. Failure to do so can result in penalties, including fines and imprisonment.
The other options are incorrect because they are not the current Companies Act in the United Kingdom. The Companies Act 1936 was the previous Companies Act, and the Companies Act 2012 and Companies Act 2013 were both superseded by the Companies Act 2006.
