• B

• C
  5% (2)
• D
  18% (7)

Explanation

Option B is incorrect because modern API gateways support both synchronous and asynchronous flow control methods, not synchronous only - they can handle message queuing, event-driven patterns, and async callbacks, which are essential for scalable enterprise architectures. Options A, C, and D are all accurate: API gateways do simplify service architecture and enable decoupling of internal systems (A), they can integrate with function workflow services to support open API capabilities (C), and they serve as the mechanism for exposing internal enterprise services to external partners or users (D). The error in B is the absolute claim that async is unsupported, which contradicts how real-world API gateways like AWS API Gateway, Kong, and Huawei Cloud API Gateway actually function.

Memory tip: Watch for answer choices that use absolute language like "does not support" or "only" - in technology questions, these all-or-nothing claims are frequently the wrong answer, because most mature platforms are designed to support multiple modes and patterns.
