How would you describe someone who is "averse" to something?

To describe someone who is "averse" to something, the most fitting choice is having a deep-seated distaste. The term "averse" refers to a strong dislike or opposition to something, indicating that the individual actively finds the subject unpleasant or objectionable. This aversion often comes from personal experience or a profound preference against whatever they are averse to, hence the description of a "deep-seated distaste."

The other options do not align with the meaning of "averse." Being willing and eager would imply a positive inclination toward something, which contrasts sharply with aversion. Completely indifferent suggests a lack of feelings or opinions, neither liking nor disliking, which doesn't capture the active dislike implied by aversion. Finally, being unaware and unbothered suggests a lack of engagement or notice toward the subject, which is inconsistent with the idea of being averse, as aversion typically involves a conscious and strong reaction against something.
