Correct option is D
A web address (URL) cannot contain the @ symbol. While web addresses can include alphabets, digits, and the dot (.) symbol, the @ symbol is reserved for email addresses and cannot be used in web addresses as part of the domain name or path.
Important Key Points:
1. Alphabets and digits are commonly used in domain names and URLs.
2. The dot (.) symbol is used to separate different parts of the domain (e.g., "www.example.com").
3. @ symbol is not valid in web addresses except in the context of email addresses.
Knowledge Booster:
· Alphabets: Web addresses often use alphabets to create domain names (e.g., www.example.com).
· Digits: Web addresses can also include numbers (e.g., 192.168.0.1 in IP addresses).
· Dot (.) symbol: The dot is used to separate different parts of a web address, such as the protocol and domain name.
