Select the email address from the following:-

- Generally, compelling valid email address characters consist of an email prefix and valid email domains, both in acceptable formats.
- The prefix appears to the left of the @ symbol, and the domain appears to the right of the @ symbol.
- Without this, email domains are not valid.
- For example, in the address, "support@microsoft.com", "support" is the email prefix, and "@microsoft.com" is the domain.
- "www.bobsmith.com" and "www.bobsmith.gmail.com" are an example of a URL.
- "Bob Smith@gmail.com" is an invalid e-mail id because there is a space between Bob and Smith.
- Hence, Bobsmith21@gmail.com is a valid email address.
