Hint: A letter is a written message that can be handwritten or printed on paper. It is usually sent to the recipient via mail or post in an envelope, although this is not a requirement as such.

Complete answer:
To send business or employment-related emails, it is mandatory to close them professionally. To know the proper answer let us analyze the given options. It is very unprofessional to end a message without closing. It should always be included in a formal email even if you have an email signature. Closing is a perfect way to end a letter in a polite way.
Option (A) See you Soon – It is an incorrect answer. See you Soon is an example of unprofessional closing. Never use this to end a formal message. These casual phrases are apt for ending letters for your friends.
Option (B) With respect- It is an incorrect answer. With respect can be used for addressing government officials. This phrase is not fit for every type of business-related email. If someone has to make some request or give gratitude, this is suitable for it.
Option (C) Regards- It is a correct answer. Regards are the perfect way to end any formal letter. Most people use regards for every business-related email because it is appropriate in almost all business situations. It symbolizes Politeness. It is a good option to use this by sending both professional and personal emails. For example, it is suitable for communicating with a co-worker as well as with any senior.
Option (D) Best- It is an incorrect answer. Best is used when a letter is less formal or you are sending a message to someone outside your work. Undoubtedly, it is used in communicating professionally but it is suitable to address someone with whom you are talking frequently.

Therefore the correct answer is option ‘C’.

Note:
- Every professional email should end with a closing remark. Here are some examples of common formal closings- Sincerely, Thank You, With appreciation, Best Wishes.
- Common semi-professional closings are- Cheers, Faithfully, warmly etc.
- Make sure not to use these phrases in any business-related emails- Talk soon, Love, Hugs, Emoticons etc.
