Which service consultant addresses their concerns about management more effectively?

Service Consultant B effectively addresses their concerns about management by demonstrating a proactive approach to communication and problem-solving. This consultant likely engages in constructive discussions with management that focus on specific issues and potential solutions, rather than merely voicing dissatisfaction. This kind of approach fosters a collaborative environment where management is more receptive to feedback and can make informed decisions based on the consultant's insights.

In contrast, other choices imply that either the first consultant does not effectively address management concerns, or that both consultants may lack the effective communication skills needed to advocate for their needs. This diminishes the influence of Consultant A's efforts if they are not as impactful as those of Consultant B, who clearly stands out by taking initiative and providing valuable input that can lead to positive outcomes for both the service team and the management.
