A message readdressal refers to a message transmitted to which of the following?

A message readdressal specifically pertains to a situation where the original message is sent to a different entity that was not intended to receive it initially. This may occur for various reasons, such as a change in operational needs or ensuring that all relevant parties are informed about the message's content.

In contrast, the other options describe different actions regarding message handling. A corrected copy suggests edits made to an original message, which does not align with the definition of readdressal, as this involves modification rather than redirection. A duplicate copy due to illegibility involves resending the same content for clarity, which again does not include changing the destination of the message. The option referring to a message returned for additions or deletions focuses on modifications rather than changing the recipient of the communication.

Thus, a message readdressal is characterized by its transmission to an entity not originally included in the draft, making that the correct response.
