Final answer:
A letter is most likely to be fraudulent if it is signed by only one person, addressed to an individual instead of a department, a photocopy of an original letter, or written on outdated company letterhead.
Step-by-step explanation:
A letter is most likely to be fraudulent if it exhibits any of the following characteristics:
- It is signed by only one person: Authentic letters typically include the signatures of multiple individuals, such as the sender and recipient, to validate their authenticity.
- It is addressed to an individual, rather than a department: Legitimate business correspondence is often sent to specific departments or teams rather than individuals.
- It is a photocopy of an original letter: Fraudulent letters may be duplicated to deceive the recipient into believing they are genuine, as photocopies lack the original letter's unique features.
- It is written on outdated company letterhead: Genuine letters are usually created using current company letterhead that includes up-to-date logos, contact details, and other relevant information, whereas fraudulent letters may use outdated materials.
