You're welcome.

To determine the correct placement of commas in the sentence "Three Skeleton Key" got its name as the narrator tells us from three escaped convicts, we need to analyze the structure of the sentence.

The sentence contains an introductory phrase, "as the narrator tells us," which provides additional information but is not essential to the main idea of the sentence. Therefore, a comma should be placed after this introductory phrase to separate it from the main clause of the sentence.

Option C, which suggests adding a comma after "as," is the correct answer. So, the correct placement of commas in the sentence is:

"Three Skeleton Key" got its name, as the narrator tells us, from three escaped convicts.
