The angular dispersion produced by a prism does what?
Has no relation with average refractive index
Increases if the average refractive index decreases
Increases if the average refractive index increases
Remains constant whether the average refractiv index increases or decreases

Conceptually, this is easy to understand if you know that the angle of refraction increases as the index of refraction increases. For a prism, the angle between different colors of light depends on the angle the light was refracted by; more refraction = more dispersion. Putting 2 and 2 together, Greater index = more dispersion.
