Final answer:
The disadvantage of traditional forms of written communication is inefficiency, as it refers to slow and cumbersome exchange of information compared to modern electronic methods. The correct answer is option c.
Step-by-step explanation:
When considering the disadvantages of traditional forms of written communication, it is important to look at options such as lack of documentation, ambiguity, inefficiency, and lack of formality. Traditional written communication methods can indeed have the formality that is often required in business and academic contexts.
However, one significant drawback is inefficiency, which refers to the often lengthy process of sending and receiving messages, the inability to quickly edit or revise said communications, and the time it takes for the recipient to receive the message. This can be contrasted with modern electronic methods of communication, which tend to be quicker and more adaptable to rapid changes and interactions.
Ambiguity in traditional written communication can also be problematic, as it can lead to misunderstandings if the message is not clear. However, this is not necessarily inherent to the medium of traditional writing itself but can occur in any form of communication if not carefully composed. Lack of documentation is typically not an issue with traditional writing, as it inherently provides a physical record of communication, and a lack of formality is also not characteristic of traditional writing, which, as mentioned, tends to follow formal structures and protocols.
Therefore, the correct option in this case is c. Inefficiency.
