The document which contains the internal regulations of a limited liability company is the "Articles of Association." The Articles of Association are a legal document that outlines the rules and regulations governing the internal management of a limited liability company. The document typically includes provisions relating to the company's objectives, share capital, and the rights and duties of the company's directors and shareholders. The Articles of Association are separate from the Memorandum of Association, which is another legal document that sets out the company's constitution, including its name, registered office, and objectives. While the Memorandum of Association outlines the company's external relationships with third parties, such as customers, suppliers, and lenders, the Articles of Association govern the internal relationships between the company's directors and shareholders. Therefore, the correct answer is "Article of Association."
