Correct option is C)

A thick lens can be considered to be a stack of prisms. Light, as it passes through a thick lens bends more because it has to travel more distance through the lens material. Different colors bend by different angles due to different refractive indices. Therefore, chromatic aberration is observed. 
Thus, assertion is correct and reason is incorrect.
