What part of the IPsec protocol provides authentication and integrity but not privacy?

EXPLANATION

In computing, Internet Protocol Security is a secure network protocol suite of IPv4 that authenticates and encrypts the packets of data sent over an IPv4 network. Because of the complexity or immaturity of the IP security protocols, the initial IPv4 was developed without or barely with security protocols such that the IP version was incomplete, open or left for further research development.
The authentication header provides authentication so that the receiver can be confident of the data source. It does not use encryption, so it does not provide privacy.
