Explanation:

A non - restrictive relative clause (in this case, "who ran in circles around the circumference of the tree") should be set off by commas. The first option correctly places commas before and after the non - restrictive clause. The second option has an incorrect comma placement (only one comma). The third and fourth options have incorrect comma placements that disrupt the natural flow of the sentence.

Answer:

The squirrel, who ran in circles around the circumference of the tree, chattered angrily at the curious cat.
