A)the calculated difference between the highest score in the class and the lowest score
B)how much each student's particular approachability score is due to genetic differences

Heritability refers to the extent to which a trait is due to genetic differences within a population. Therefore, the best choice to describe the heritability of the trait is C, which refers to the variation within the class that is due to genetic factors. Choices A and D do not relate to heritability, and choice B may be too specific as it refers to each individual's score, rather than the variation within the class as a whole.
