What will you need to change to make the message appropriate for both a colleague and your supervisor?
a. give a complete summary of the survey plan in case your colleague has forgotten what you talked about.
b. describe what you had for lunch and what the kids look like in detail.
c. make the message more formal, remove the personal discussion, and give more specifics about the survey plan.

Letter c is correct. Make the message more formal, remove the personal discussion, and give more specifics about the survey plan.

Explanation:

A poorly written message can damage an employee's image within an organization. So when sending a message to a colleague and a supervisor at the same time, it is ideal that personal discussions are removed and the focus is only on business matters. Formality must be maintained to convey respect and professional attitude in order to avoid communication noise and achieve clarity in the message.
