Because He Has Received B+'s on His Last Three Examinations

Because he has received B+'s on his last three examinations, Leo really wants to make an A in his personality psychology class. However, because he has received three D's on his last three history examinations, he really doesn't care what type of grade he makes in his history class, as long as it is not a D- or less. Leo's views about the grades represent differences in their:

A) Subject value by his parents
B) Expectancy of the reinforcement value
C) Subjective assessment of the limited-domain expectancies
D) Objective evaluation of the limited-value expectancies
