Reply All is required for emails with CC

Assume that when Mr. A sends an email to Mr. B, it is cc'd to Mr. C.
When Mr. B replies to Mr. A, he needs to Reply All (Reply to all) Otherwise the reply will be sent only to Mr. A.
Mr. A thinks "Mr. B responded back".
Often assume that "Mr. C has received a reply as well".
Mr. C thinks, "I haven't heard back from Mr. B yet."
There's no way to know the email is being returned until you check with Mr. A.
This situation occurs because of the design of the email tool.
Not generated if you use a mailing list or group chat.
