B)Population B
C)Population C
D)All of these populations will respond in a similar manner.
E)This cannot be determined from the information given.

A higher narrow-sense heritability value means that a larger proportion of the variation in the trait is due to genetic factors, indicating that the trait is more heritable. Therefore, population C with a narrow-sense heritability value of 0.8 is more likely to respond better to selection experiments as there is a greater potential for genetic improvement of the trait in this population.
