Which behavioral modification system is commonly used in training?

Customer Relationship Management (CRM) is primarily a business strategy focused on managing a company's interactions with current and potential customers. It is not a behavioral modification system used in training contexts.

Cognitive Behavioral Therapy (CBT) utilizes techniques based on cognitive and behavioral principles to modify thoughts and behaviors, making it an effective approach in therapeutic contexts. However, it is not a training-specific behavioral modification system.

Activity-Based Curriculum Development (ABCD) refers to the method of structuring educational programs around specific activities. While it may involve behavioral modifications, it is more a curriculum development approach than a system that directly targets behavior change through structured training.

Fire Management Assessment (FMA) pertains to evaluating and managing fire-related incidents or strategies. This is crucial for operational effectiveness but doesn't serve as a behavioral modification system in training contexts.

The correct choice should have contextualized a training method that directly impacts behavior, like CBT, which focuses on implementing changes through structured interventions. In training, behavioral modification systems that rely on reinforcement principles and structured tasks would typically be more relevant, particularly in fields such as emergency services where behavior directly influences outcomes.
