c. a protocol that allows computer systems to exchange key agreement over an insecure network.
d. a protocol that secures ip communications by authenticating and encrypting each ip packet.

The correct answer to the following question will be Option d.

Explanation:

A protocol that is used to set authenticated and secure communication between two peers is termed as Internet Key Exchange (IKE), sometimes depends on the versions such as IKEv1 or IKEv2. We can also say that 'the method of exchanging keys for authentication and encryption over unsecured medium and can secure all IP communications'.

The other three options are not related to these types of working or IKE doesn't refer to those works. So, option d is the correct answer.
