Answer is Right!
Answer is Wrong!
The correct answer is A. System name.
An email address is a unique identifier that is used to send and receive emails. It is composed of three parts: the username, the domain name, and the @ (at symbol). The username is the name of the person or organization that owns the email address. The domain name is the name of the company or organization that hosts the email server. The @ (at symbol) separates the username from the domain name.
System name is not a component of an email address. It is the name of the computer or device that is used to access the email account.
