Selected Answer: C
Why C is the “best-fit” trio Legacy EDI support: EDIFACT covers traditional supplier EDI flows without forcing them to re-tool. File-based bulk transfer: XML over SFTP handles large batch files securely with straightforward scripting support. Modern real-time API: JSON/REST over HTTPS gives suppliers a lightweight, developer-friendly option for interactive use cases. Together they satisfy security, interoperability, and ease-of-use across the heterogeneous supplier ecosystem.

I think C. XML over ActiveMQ does not satisfy requirement of being secure. It can authenticate but not encrypt message itself.
