The incorrect statement about ‘Revolution’ is option 2, which states that revolution implies change within the system`s rules.

Option 1, "Revolution implies change of the system itself," is accurate. A revolution is a significant and often radical change in the political, social, or economic systems. It involves a profound transformation of the established order.

Option 3, "Attempts at revolution often produce violence," is also correct. Revolutionaries may resort to violence as a means to overthrow the existing system and bring about the desired change. However, it is important to note that not all revolutions involve violence, as some may be more peaceful or nonviolent in nature.

Option 4, "No type of political system is immune to revolution," is true. Revolutions can occur in any type of political system, whether it is authoritarian, democratic, or any other form. History has shown that even stable and seemingly secure systems can be vulnerable to revolutions.

In conclusion, option 2 is incorrect because revolution implies a change that goes beyond the existing system`s rules, often involving a complete transformation rather than working within the established framework.
