Show answer & explanation
Correct answer: D
The question asks which statement is NOT valid. An e-mail address must contain exactly one @ symbol, so the statement that it can have any number of @ symbols is false (invalid). The other statements are true: an address can contain multiple dots with no fixed upper limit (only consecutive dots and a leading/trailing dot in the local part are disallowed), and ordinary e-mail addresses cannot contain spaces. Hence the statement "E-mail address can have any number of @ symbols" is the invalid one.
