Correct answer: RESTCONF, NETCONF.
Why this is the answer
NETCONF and RESTCONF are the primary protocols used to transport YANG data models. NETCONF is an XML-based protocol designed specifically for network device configuration and monitoring, using RPCs (Remote Procedure Calls) to exchange YANG-modeled data. RESTCONF is an HTTP-based protocol that provides a RESTful interface for interacting with YANG data models, offering a more web-friendly approach. While TLS and SSH provide secure transport layers, they are not application-layer protocols for transporting YANG data directly; NETCONF often runs over SSH, and RESTCONF over HTTPS (which uses TLS). HTTPS is a secure transport, but RESTCONF is the protocol that defines how YANG data is structured and exchanged over it.
