Cisco IOS XE supports the Yet Another Next Generation (YANG) data modeling language. YANG can be used with the Network Configuration Protocol (NETCONF) to provide the desired solution of automated and programmable network operations. NETCONF(RFC 6241) is an XML-based protocol that client applications use to request information from and make configuration changes to the device. YANG is primarily used to model the configuration and state data used by NETCONF operations.

I dont think C is a correct answer. D looks to be the most correct answers, as it matches an article on NetworkWorld: "NETCONF is the standard for installing, manipulating and deleting configuration of network devices while YANG is used to model both configuration and state data of network elements." E is describing NETCONF as an alternative to RESTCONF, but not YANG (The NETCONF DML) itself.
