Answer: In GCP console, click Traffic Splitting and direct 100% of the traffic to the previous version.
The correct answer is **C** because the most efficient way to revert to a functioning state is by redirecting all traffic to a previously deployed version using Traffic Splitting in the GCP console. This method allows for immediate redirection without the need for command-line interventions, which may not support rollback or revert features as indicated in options A and D. Option B is incorrect as the GCP console does not offer a direct Rollback button for this purpose. Traffic splitting is a versatile feature that not only facilitates quick rollbacks but also supports A/B testing and controlled feature rollouts by distributing traffic among multiple versions.
