Answer: The correct answer is option C (commas). Explanation: In formal writing, when stating the non-essential information such as appositives, adjectival phrases, or adverbial phrases, the more suitable punctuation is the use of COMMAS.

Use a comma (or a pair of commas) to set off elements that are nonessential (also called nonrestrictive). A phrase or clause is nonessential if it can be removed without changing the main idea of the sentence; a nonessential element just adds a relatively unimportant detail.

Commas, parentheses and dashes are used in writing to mark these comments as extra-information or as an interruption to the sentence. Commas are the preferred way to set off information from the rest of the sentence. However, parentheses and dashes are used too.

When the words after yes and no “echo” the words of the question, use a comma.

Yes, you need a comma after Yes or No “Yes” and “no” are always followed by a comma at the start of a sentence.

Commas—sometimes paired with semicolons—are traditionally used to set off adverbs such as however, therefore, and indeed. When the adverb is essential to the meaning of the clause, or if no pause is intended or desired, commas are not needed.

Even if the idiom “No thank you” is commonly used, it’s much less polite. It suggests “I’m not thanking you” or “No thank you for you.” If you don’t have a problem with the questioner interpreting your response that way, then it’s okay to leave the comma out. Otherwise, it should be included.

No thanks is not more rude than no thank you, it is just more informal. Someone could interpret that as rude, if they are very touchy, but no thanks is definitely not rude to say.

An expression of gratitude for the offer of something that one does not want or is not interested in. Often used sarcastically or impolitely.

Yes, many thanks is perfectly proper, grammatical, standard English. It is appropriate to use wherever “thanks” (as opposed to “thank you”) would be acceptable. As Martha says, many thanks is perfectly idiomatic.

To be polite it’s always good to say “Sure, I would like to …” or “Sure, that would be nice…” Which is still dependent on how you say these words. If you say them sarcastically then it would be rude. Sure is dependent on how you sound when using it to agree to something.

“Anyways” is incorrect—it’s “anyway.” I don’t think that “Thanks anyway” is rude unless perhaps the person went out of his or her way to help you. Then the person deserves a better thank you.

Take, for instance, the phrase “to be clear.” Although at face value it can be used to say that one is trying to clarify what is discussed, used in the wrong way, it can be rude to use it in certain contexts.

Synonyms

• i want to make it clear.
• let me be clear.
• make that clear.
• be clear.
• be clear here.

When someone is “clear” about something, it means they have made (something) easy to understand because they do not want to be misunderstood. When a person says “Just so I’m clear”, it is like saying “Just to be certain that you do not misunderstand me, I’m going to explain this further (or restate what I said before)”
