Which of the following statements about e-mail is true?

Answer: Option B

E-mail is an electronic method of sending messages and files through the internet. An e-mail contains different fields such as To, CC, BCC, Subject, and attachments.

Let us examine each option carefully:

Option A: An e-mail cannot contain both pdf and zip file as an attachment

This statement is false because an e-mail can contain multiple types of attachments at the same time, including PDF, ZIP, images, documents, videos, and more.

For example, a user can attach both a report.pdf file and a documents.zip file in the same e-mail.

Option B: CC field can be empty in an email

This statement is true.

The CC (Carbon Copy) field is optional in an e-mail. It is used when the sender wants to send a copy of the message to additional recipients for information purposes.

An e-mail can still be sent even if the CC field is left blank.

Option C: E-mail cannot have more than 5 attachments

This statement is false because there is no fixed rule limiting e-mails to only 5 attachments.

Most e-mail services allow many attachments as long as the total file size remains within the allowed limit.

Option D: To field in email cannot be blank

This statement is generally considered false in such objective questions because an e-mail can also be sent using only the CC or BCC fields in many e-mail systems.

Therefore, the clearly correct statement among the given options is:

Option B: CC field can be empty in an email.
