Answer:
The main problem with the critique is A. It is not objective.
Explanation:
A person is offering their critique concerning a speech that was related to horses. Notice that this person is not focusing on the speech itself, on how efficiently it conveyed the message, on how well-organized and coherent it was, etc. This person is focusing on his/her own personal preferences and pre-concepted ideas. He/She has allowed the fact that he/she doesn't like horses to interfere with his/her opinion of the speech. This person has also let his/her personal feelings toward the speaker influence his/her judgment. As we can see, his/her critique is highly subjective - permeated with biases. Therefore, the main problem with it is A. it is not objective.
