Concept:Pressure groups use different methods to influence government, but only disruptive methods can threaten the stability of the state.
Explanation:Strikes involve work stoppages and mass protests, often organised by trade unions or pressure groups.
When strikes become widespread or prolonged, they can halt production and disrupt essential services, damaging the economy.
They can also lead to social tensions, clashes with authorities, and public disorder.
If strikes target government policies, they create political instability by challenging the legitimacy of the government.
By contrast, lobbying, symposia, and debates are peaceful, lawful, and constructive methods of persuasion; they do not undermine the economic, social, or political order of the state.
Answer:Strikes (Option C) is the correct answer.
