Answer: The right answer is the B) Insert commas after "angry," "bitter," and "hateful."
Explanation: Just to elaborate a little on the answer, it can be added that there are two instances in this sentence that make appropriate the use of commas. On the one hand, commas must be used to separate independent clauses when they are joined by a coordinating conjunction, such as "but." Therefore, you need a comma after "hateful." On the other hand, commas must also be used to separate three or more words in a series, as in "angry, bitter, and hateful."
