Comprehensive and Detailed in Depth

To identify whether conflict is causing high turnover, the organization needs methods that directly collect employee feedback about workplace dynamics.

Option A (Survey): Correct, as surveys can ask targeted questions about conflict and its impact on employees' decisions to leave.

Option B (Screening): Screening is part of recruitment, not suitable for assessing turnover causes.

Option C (Focus group): Correct, as focus groups allow for in-depth discussions with employees to explore conflict as a turnover factor.

Option D (Needs analysis): This identifies training gaps, not conflict-related turnover causes.

Option E (Performance appraisal): This evaluates individual performance, not department-wide conflict issues.
