I think its C or D

C is correct.

Commas are needed to separate two independent clauses joined by and.

The correct answer is C. Commas are needed to separate a list of three or more items in a sentence. This rule is known as the Oxford comma. Option D is incorrect because you should use a comma to separate two complete sentences joined by "and".

To determine the accurate statement regarding the use of commas, we can examine each option and explain how to get the answer.

A. A parenthetical use of commas is usually confusing to the reader.
To verify if this statement is accurate, we can consider the purpose of parenthetical commas. Parenthetical commas are used to set off non-essential information in a sentence. If the information enclosed by commas can be removed without changing the overall meaning or structure of the sentence, it is considered parenthetical. Parenthetical commas can help provide additional context or clarification. However, it is worth noting that excessive use of parenthetical commas can make a sentence confusing. Therefore, option A is not completely accurate.

B. There is no need for commas that indicate added details in a sentence.
This statement is not accurate. Commas are commonly used to separate added details or non-essential information in a sentence. These details can be set off by commas to make the sentence clearer and more organized.

C. Commas are needed to separate a list of three or more items in a sentence.
This statement is accurate. When listing three or more items in a sentence, commas are necessary to separate each item. For example: "I bought apples, bananas, and oranges." The comma before the conjunction "and" is known as the Oxford comma and is commonly used, although its usage varies depending on the style guide or preference.

D. You should not use a comma to separate two complete sentences joined by "and."
This statement is not accurate. When two complete sentences are joined by a coordinating conjunction like "and," a comma is typically used before the conjunction to indicate a slight pause or separation between the two sentences. For example: "I went to the store, and I bought some milk." This is known as a compound sentence, and the comma is essential for correct punctuation.

Based on the explanations above, the accurate statement regarding the use of commas is C: Commas are needed to separate a list of three or more items in a sentence.
