False is the correct answer for the above question.
Explanation:
"Electronic cover letter" is a cover letter which is used with a resume or CV to state the additional information of that CV or resume. It is a cover letter attached to some documents. Just like, If a person bought some books then there is also a book cover attached with it which states about the book author and some other details about the book.
Just like, when a person writes a resume or CV then there is also needs a cover letter which is called "Electronic cover letter". To attach the cover letter a user needs a resume and to send that a user needs an email. So there are two important things to send the cover letter-- email address and document. But the question states that only email is important which is not correct. So the question statement is a false statement.
