Answer:
last one check it and the second one
Explanation:
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.
Answer: Strong 128-bit encryption.
Explanation: An individual character corresponds to 8 bits . So if there are 16 characters then,
16
8=128 bits keys
This makes the 128 bit key encryption the strongest amongst all other options.It is strongest because it is almost impossible to decode the 128-character key by any method e.g.-brute-force method.
Other options are incorrect because the characters given by the other bits are as follows: 
=32 characters
=64 characters
=128 characters
Thus, the strongest character key is of 128 bits. for cipher.
