Which of the following is a disadvantage of letters?

• A. Can be sent to many people, flexible, information expressed in an understandable way, and provides a record
• B. Flexible and easy to replace
• C. Provides immediate feedback
• D. Can take time and effort

Answer: (D)

Letters as a communication method often involve more steps and slower processes. Writing a formal letter, addressing it, adding a stamp, and posting it all take time, and the recipient’s reply comes back only after the postal system delivers it. This can delay decisions, slow workflows, and add costs for postage and materials. The need for careful wording and formatting also means more effort is required compared with faster digital methods. So, the main drawback here is that letters can take time and effort to use effectively.
