The best answer is A. Release management.

In continuous delivery, code moves frequently from development toward production, but the key control point that connects development output to live production deployment is release management. ISACA explains that continuous delivery takes integration output that has met release criteria and updates the application in production. That means the practical bridge between development and production is the release process that governs packaging, approval, timing, and movement into production.

Option C. DevOps is closely related, but it is broader than the specific connector. ISACA describes DevOps as focusing on automation and integration of processes before and after software release into production. That makes DevOps the broader operating model, while release management is the specific connector between development and production in the delivery pipeline.

Option B. Log management is important for monitoring and troubleshooting, but it does not connect development to production.

Option D. Data management is also important, but it is not the delivery bridge in this context.

Therefore, the correct answer is A, because release management is the function that controls and enables the movement of approved changes from development into production.
