(D) The normal shift produced by a glass slab of thickness $t$ and refractive index $\mu$ is given by $\Delta x = t(1 - 1/\mu)$.Since the shift $\Delta x$ is inversely proportional to the refractive index $\mu$ (as $\mu$ increases,$1/\mu$ decreases,and $1 - 1/\mu$ increases),the shift is minimum for the color with the minimum refractive index.According to Cauchy's formula,the refractive index $\mu$ is highest for violet and lowest for red light $(\mu_V > \mu_R)$.Therefore,the shift is minimum for red light,meaning the red letter will appear to be raised the least.
