The correct answer is an automated welcome bot message that prompts the new employee to complete an introduction workflow, which is then automatically shared with the team. The client wants a warm onboarding experience where employees share fun and useful information with coworkers, and the key word is automated . Option A satisfies both requirements: it initiates the experience through Slack automatically and uses a workflow to collect and distribute the introduction consistently. Option B relies on managers to prompt the employee, which introduces inconsistency and is not fully automated. Option C depends on a manual manager message and asks the employee to post in a company-wide welcome channel, which may be too broad and less targeted than sharing with the employee’s team. Option D provides a private welcome but fails to include the employee-sharing component the client requested. Workflow-based onboarding is stronger because it standardizes the experience, reduces manager workload, and makes the new hire’s introduction visible in the right collaboration context.
