A.
Authentication

Explanation:
Authentication is the act of establishing or confirming something (or someone) as authentic, that is, that claims made by or about the subject are true (“authentification” is a variant of this word). This might involve confirming the identity of a person, tracing the origins of an artifact, ensuring that a product is what its packaging and labeling claims to be, or assuring that a computer program is a trusted one. Authentication is a process of verifying the user. The accuracy of the authentication can be determined by the number of factors used for the authentication, such as the following:
One-factor authentication
Two-factor authentication
Three-factor authentication
Multi-factor authentication
What is Open System Authentication?
Open System Authentication (OSA) is a process by which a computer can gain access to a wireless network that uses the Wired Equivalent Privacy (WEP) protocol. For OSA to work, the service set identifier (SSID) of the computer should match the SSID of the wireless access point. The process occurs in three steps:
1.First, the computer sends a request for authentication to the access point.
2.The AP authenticates the computer.
3.Finally, the computer accepts the authentication code and becomes part of the network as long as the session continues and the computer remains within range of the original access point.

What is shared key authentication?
Shared key authentication is an authentication method specified in the 802.11 standard. In this authentication, a static WEP key should be configured on the client. The shared key authentication has the following processes:
1.The client makes a request to the access point for shared key authentication by sending an authentication request.
2.The access point sends authentication response to the client. Authentication response contains challenge text in a clear text format.
3.The client uses its locally configured WEP key to encrypt the challenge text and replies with a subsequent authentication request.
4.If the access point can decrypt the authentication request and retrieve the original challenge text, then it responds with an authentication response that allows the client to access the network.
