if it not c it is a. because the commas is in the right spot?

Yes, "a" is correct -- TWO commas needed when it's in the middle of a sentence.

Yes, you are correct. Sentence c, "Miep the one who helped them, stopped coming," correctly uses commas with appositives.

To identify the correct answer, we need to understand what an appositive is and how to punctuate it with commas.

An appositive is a noun or noun phrase that renames or provides additional information about another noun right beside it. To set off the appositive from the rest of the sentence, we use commas.

In sentence c, "Miep" is the appositive because it renames or gives additional information about "the one who helped them." The commas surrounding "the one who helped them" correctly separate it as an appositive phrase.

In contrast, sentences a, b, and d have incorrect comma usage with appositives.

a) In "Mr. Van Daan’s son, Peter, spent a lot of time with Anne," the comma after "son" is unnecessary. We don't need to separate "Peter" as an appositive because it is already clear that the son's name is Peter.

b) In "Margot, Anne’s sister is the oldest," there should be commas before and after "Anne's sister" to correctly set it off as an appositive phrase.

d) In "Mrs. Van Daan the selfish woman, always defends, her husband," there are multiple errors. Firstly, the phrase "the selfish woman" should be in between commas as an appositive. Secondly, the second comma after "always defends" is unnecessary.

So, the correct sentence is c) "Miep the one who helped them, stopped coming."
