Which algorithm is an NGE hash function?
SHA-2 is an NGE (Next Generation Encryption) hash function. NGE algorithms are recognized for providing a higher level of security, and SHA-2, which includes variants such as SHA-256, SHA-384, and SHA-512, is widely accepted as part of this suite. MD5 and SHA-1 are older hash functions and are not considered secure enough for current use, while HMAC is a different type of cryptographic algorithm.
Aswer D https://www.cisco.com/c/en/us/support/docs/security-vpn/ipsec-negotiation-ike-protocols/116055-technote-ios-crypto.html NGE algorithms are integrated into Internet Engineering Task Force (IETF), IEEE, and other international standards. As a result, NGE algorithms have been applied to the most recent and highly-secure protocols that protect user data, such as Internet Key Exchange Version 2 (IKEv2). Types of cryptographic algorithms include: Hash - Secure Hash Algorithms (SHA)-2 (SHA-256, SHA-384, and SHA-512)

This has to be a typo. I've never heard of SHA-2 and no reference to it anywhere. HMAC is the only feasible answer, if it really is meant to say SHA-2.
https://en.m.wikipedia.org/wiki/SHA-2 The algorithm is called sha-2, the digit size is 256, etc.
