A pressure group which resorts to violence as a means of pressing home its demands is described as

Step 1: Analyze the question The question asks which type of pressure group uses violence to press its demands.

Step 2: Explain the concept Pressure groups are classified by structure and methods:

• Anomic pressure groups: These are spontaneous, unorganized groups that act outside normal channels. They often use violence, riots, demonstrations, or assassinations. Examples include rioting mobs and militant youth groups.
• Associational pressure groups: These are formally organized groups with defined membership and procedures, such as the Nigerian Bar Association, the Nigerian Medical Association, and trade unions. They usually use lawful means like petitions, lobbying, and negotiation.
• Labour groups: These are a type of associational group (e.g., NLC, ASUU) that represent workers. They use strikes and negotiation, not necessarily violence.
• Attitudinal groups: These focus on promoting a cause or changing attitudes, such as environmental or human rights groups. They are not defined by violence.

Step 3: Apply to the question The key phrase is "resorts to violence." The type of pressure group defined by spontaneous, often violent, extra-constitutional action is the anomic group. The other options are generally peaceful and organized.

Step 4: Answer The correct option is A. anomic.

Tip: Think "anomic = anarchic". The word "anomie" means a breakdown of order, so anomic groups are the ones that disrupt order through violence. Associational = Organized and lawful.
