The requirement that an operator must have habits and experiences that demonstrate competence in safety is fundamental to the role of a Grade B engineer. This is because Grade B engineers are typically entrusted with operating boilers under various conditions where safety is paramount. They must possess not only the technical skills necessary for operation but also a keen understanding of safety protocols and best practices to prevent accidents and ensure safe operation.

In contrast, other grades might have varying levels of responsibility regarding safety competencies. Grade A engineers may have more extensive training and experience compared to Grade B, potentially allowing for a broader scope of duties. Grade C engineers, while still important, generally operate under more supervision and might not face the same level of responsibility regarding safety that a Grade B engineer does.

Therefore, the emphasis on safety habits and experiences specifically aligns with the role of the Grade B engineer, making this the most appropriate choice. This ensures that they can effectively manage the responsibilities expected of them while maintaining the highest safety standards.
