Which protocol is widely used in IoT because it is a lightweight publish-subscribe messaging protocol suited to low-bandwidth, constrained devices?
MQTT is the correct answer. It is a lightweight publish-subscribe messaging protocol built for constrained devices and low-bandwidth networks, which is why it is widely adopted in IoT, unlike SMTP for email or FTP for file transfer.

- BMQTTCorrect
- CFTP
- DHTTP/1.0 only
Explanation
MQTT is a lightweight publish-subscribe protocol designed for constrained devices and unreliable networks, so it is common in IoT. SMTP is for email and FTP for file transfer, so they are not the IoT messaging standard.
