Which of the following would be the most appropriate way to address and greet your teacher, mr. joseph herman, in an email? hi joseph, how u doin? ? dear joseph herman, how are you dear mr. herman, i hope you’re doing fine. dear joseph, i hope you are doing great.

To determine what would be the most appropriate way to address and greet your teacher during an email, we should eliminate some greetings, such as:
"Yo wassup?", "How  u doin?", or any other grammatical and socially inappropriate errors.
Let's look at our first option.
"Hi Joseph, How u doin??". This is incorrect as it is not appropriate to address anyone in such a manner and with grammatical errors.
Let's look at our second option.
"Dear Joseph Herman, how are you doing!!". This was on the right path, but didn't end well. The ending of the message, "how are you doing!!" is incorrect punctuation, and has too much excitement.
How about our third option?
"Dear Mr. Herman, I hope you're doing fine.". This is a great email. It has perfect punctuation, grammar, and is appropriate.
What about our fourth?
"Dear Joseph, i hope you are doing great.". This is a good email, but has incorrect punctuation.
Your answer is C.) Dear Mr. Herman, I hope you're doing fine.
