Answer:
C. Brady has a highly ambivalent attitude toward her math course.
Step-by-step explanation:
Ambivalent attitude refers to a mixture of conflicting emotions that a person can feel toward a certain thing. Usually this conflicting emotions occurred when an object / events provided both positive and negative results in a person's life.
In Brady case, the math course made her learn a lot of thing (which is a positive result for her life), but at the same time it took a lot of her free time due to the homework's (negative results for her life). This explains the ambivalent attitude.
