The Agent-to-Agent (A2A) Protocol Overview describes A2A as a standardized framework for cross-vendor agent discovery and communication. The documentation specifies:

“A2A enables secure, interoperable communication between AI agents across vendors, platforms, and ecosystems, using standardized APIs and schemas for message exchange and capability discovery.”

This allows AgentForce agents to interact with external AI systems or partner agents while maintaining data governance and identity controls.

Option B is incorrect because auto-onboarding without contracts or trust verification is not supported.

Option C confuses A2A with the internal reasoning runtime used by AgentForce; A2A operates across systems, not within a single platform.

Therefore, Option A correctly defines the key benefit of the Agent-to-Agent protocol.
