B. They should offer reasons or explanations.
Step-by-step explanation:
A negative business message is a letter, memo, or email that conveys negative or unpleasant information, such as a rejection, negative evaluation, and announcement of policy changes that don't benefit the reader. The person writing this type of message should make sure to help the receiver understand and accept the news. This is why they should always offer reasons or explanations about why exactly the reader is receiving the message.
