A right-angled prism of refractive index \(\mu\)1 is placed in a rectangular block of refractive index \(\mu\)2, which is surrounded by a medium of refractive index \(\mu\)3, as shown in the figure. A ray of light e enters the rectangular block at normal incidence. Depending upon the relationships between \(\mu\)1, \(\mu\)2 and \(\mu\)3, it takes one of the four possible paths 'ef', 'eg', 'eh' or 'ei'.
Match the paths in List I with conditions of refractive indices in List II and select the correct answer using the codes given below the lists:
