Correct option is C
An email address typically follows the format "username@domain.com," where "@" separates the user's name from the hosting domain (e.g., gmail.com).
Important Key Points:
1. Standard email structure includes a username, the "@" symbol, and a domain name.
2. A valid top-level domain (e.g., .com, .org, .edu) must follow the domain.
Knowledge Booster:
· name_domain.com: Lacks the "@" symbol, making it invalid.
· name@com_domain: Incorrect domain format; top-level domain cannot be embedded.
· name.com: Not an email structure; resembles a website address.
