Correct answer: C
MQTT (Message Queuing Telemetry Transport) is a lightweight, publish-subscribe messaging protocol designed for low-bandwidth, high-latency networks. It is widely used in IoT applications because it enables efficient communication between devices with limited resources. HTTP and FTP, on the other hand, are not optimized for such environments. HTTP is primarily used for web communication and requires more bandwidth, while FTP is designed for file transfer and is not suitable for real-time device messaging. Therefore, MQTT is a valid example of an IoT protocol.
