Final answer:
The mark of "Faxed Copy" on faxed documents is uncertain as it depends on the settings of the fax machine and sender's preferences. No standardized rule requires all fax transmissions to be labeled as such. d) Uncertain
Step-by-step explanation:
Traditionally, when a document is sent via a fax machine, a header is usually printed on the top of each transmitted page. This header often includes information such as the sender's fax number, the number of pages, the transmission time, and sometimes a label such as "Faxed Copy."
However, whether a fax transmission is explicitly marked with "Faxed Copy" can vary based on the machine's settings and the sender's preferences. In general, modern fax machines and internet fax services can be configured to include or exclude such a message. Therefore, the answer to whether every faxed document is marked "Faxed Copy" is: d) Uncertain.
