The correct answer is option 4. The Attorney General of India has the right to audience in any court of law within the territory of India. This means that the Attorney General can appear and speak on behalf of the government in any court in India, including Sessions Courts, High Courts, and the Supreme Court. The right to audience gives the Attorney General the authority to represent the government and present arguments, make submissions, and defend the interests of the state in legal proceedings. It is an important role that allows the Attorney General to provide legal advice and guidance to the government and ensure that the interests of the state are protected in the judicial system.
