Which of the following is a feature of a confederation?

A confederation is a system of government where the constituent units (such as states or provinces) retain a large degree of autonomy and the central government has limited powers. Therefore, the feature of a confederation is that there is a legal right of secession, which means that the constituent units have the legal right to withdraw from the confederation if they so desire. This feature is important because it helps to prevent the central government from becoming too powerful and ensures that the constituent units have a say in the affairs of the confederation.
