Answer: gRPC-based APIs
The API requirements are HTTPS support, minimized bandwidth, and easy mobile integration. - **RESTful APIs (A)** use HTTPS and are easy to integrate with mobile apps but use text-based formats like JSON, which are less efficient for bandwidth. - **MQTT (B)** is lightweight (good for bandwidth) but is a messaging protocol, not HTTP-based, making HTTPS integration and API design more complex for mobile apps. - **gRPC (C)** uses HTTP/2 (supports HTTPS), Protocol Buffers (binary, minimizing bandwidth), and offers strong client library support for mobile platforms, meeting all three requirements. - **SOAP (D)** uses XML (high bandwidth) and is cumbersome for mobile integration. gRPC-based APIs are optimal for balancing HTTPS support, bandwidth efficiency, and ease of mobile integration.
