What is the difference between 'Reply' and 'Reply All' in terms of information management?

• A. Reply sends to the original sender; Reply All includes everyone on the thread, affecting visibility and inbox volume.
• B. Reply all removes the original sender from the thread.
• C. Reply only to the last person who replied.
• D. Reply always copies external stakeholders.

Answer: (A)

A key part of information management in email is controlling who receives your reply. When you use Reply, the message goes only to the person who sent the original email, keeping the conversation private between you and that sender and preventing others from seeing or being pulled into the thread.

When you use Reply All, your reply goes to everyone who was included in the original thread—every recipient and anyone CC’d. This maintains the full group context and ensures everyone stays informed, but it can increase visibility and inflate inbox volume for many people.

So, the difference is about who gets read it: the original sender only versus everyone on the thread. The other options describe behaviors that don’t match standard email functions.
