An incident has occurred in an organization’s core mobile banking application.

ChatOpsis the practice of conducting operational work directly through chat platforms (e.g., Slack, Microsoft Teams) integrated with automation and tooling. In this case:

Teams from multiple locations are collaborating in real-time via Slack.

They are running commands and queries directly from the chat to the delivery and monitoring systems.

This allows shared visibility, immediate context, and rapid action during incident resolution.

WhileA(Swarming) describes a collaborative incident response, it does not specifically imply integration with chat-based tools.C(Incident Management) is the overall process, andD(IT Support) is a function, but neither capture the specific ChatOps approach.

Thus,B – ChatOpsis the most accurate answer here.
