Step-by-step explanation:
The information system that supports base, wing, and work center level training management activities is the Training Business Area (TBA) (option a). The TBA is an integrated suite of web-based applications that provide the tools and capabilities to manage training requirements, course scheduling, student record keeping, and training evaluation and assessment.
For example, TBA allows training managers to track and manage training courses and resources, maintain student records, and generate reports on training activities and progress.
Other systems mentioned in the options, such as Integrated Maintenance Data System (IMDS), Management Internal Control Toolset (MICT), and Global Cyber Support Systems-Dashboard (GCSS-D), are not specifically designed for training management.
