Question

Which of the following sentences is punctuated correctly?

A. When I went into the store I saw the display right before it tumbled over.
B. When I went into the store, I saw the display, right before it tumbled over.
C. When I went into the store, I saw the display right before it tumbled over.

C. because using commas appropriately changes how you say the sentence. And in this paraphrase the comma needs to be included only in the middle of the sentence where the author pauses.
