Answer 1

The answer is the squirrel, who ran in circles around the circumference of the tree, chatted angrilly to the curious cat

Answer 2

The choice that correctly revises the sentence is A: The squirrel, who ran in circles around the circumference of the tree, chattered angrily at the curious cat.

Step-by-step explanation:

The clause above is a nonessential relative clause modifying the noun head "squirrel". As such, it is separated from the rest of the sentence with commas because it does not provide information that is considered relevant to the meaning of the sentence. If it was removed, the meaning of the sentence would be left unchanged (see 1).

1) The squirrel chattered angrily at the curious cat
