Which of the following cannot be a part of an e-mail address?
Correct answer: D. Space
- A. Underscore (_)
- B. Period (.)
- C. At sign (@
- D. Space
Explanation
Space is the only option that cannot be a part of an email address. Email addresses follow a specific format consisting of two parts separated by an "at" sign (@). The first part, called the local part, identifies the mailbox on the mail server. The second part, called the domain name, specifies the mail server that receives the email. Spaces are not allowed within either part of an email address because they can cause routing problems.
