Which version of this candidate's answer best demonstrates Effective Communication with clear ownership and impact? Version 1: "I noticed a communication gap between product and engineering that delayed features. I escalated the issue to my manager, who then organized a meeting. Afterward, the teams aligned better." Version 2: "We noticed communication issues between teams and decided to improve our meetings. We worked together to fix the problem, and collaboration improved." Version 3: "During a sprint, I saw unclear requirements from another team. I took initiative to clarify them directly with their lead, documented the changes, and shared updates with my team. This reduced rework by 15%." Version 4: "I found a miscommunication in the project and asked the project manager to handle it. The teams then coordinated better, and the project finished on time."
