In a Gmail address, what does the "@" sign separate?

Correct option is B

In a Gmail address, the "@" sign separates the username from the domain. For example, in the email address user@gmail.com, "user" is the username, and "gmail.com" is the domain. The "@" symbol is used universally in email addresses to distinguish between the local part (username) and the domain part (email provider).
Important Key Points:
1. The "@" sign is a standard separator between the username and the email service provider's domain name.
2. Every valid email address has this structure: username@domain.
Knowledge Booster:
· Username and password are not separated by the "@" sign; they are used together for authentication but are kept separate from the email address format.
· Email ID and contact number are unrelated to the structure of an email address.
· Sender and recipient are defined in the "To" and "From" fields of an email, not by the "@" sign.
· Local and international servers are not distinguished by the "@" sign; the domain specifies the email provider’s server.
