Jena Is a Bright Student, but She Can't See It

Jena is a bright student, but she can't see it. Last week, she got a B on her history test and was depressed for the rest of the afternoon. Her friends tried to cheer her up by offering to study with her next time, and reminding her that she'd done better than any of them, but it didn't help. In fact, Jena isn't just insecure about her scholastic abilities, but she also thinks she's ugly, fat, and without talent (the reality is that her looks are average, her weight is average, and she's a talented saxophone player) . Jena's explanatory style is

A) dual.
B) optimistic.
C) pessimistic.
D) social-constructivist.
