Total internal reflection can take place when light travels from
Explanation
Total internal reflection (TIR) occurs only when light travels from an optically denser medium into an optically rarer medium and the angle of incidence exceeds the critical angle. A diamond (high refractive index) to ordinary glass (lower refractive index) is a denser-to-rarer interface, so rays inside the diamond can undergo TIR for sufficiently large incidence angles. By contrast, the other three choices (water → glass, air → water, air → glass) are transitions from a rarer to a denser medium (or otherwise do not satisfy the denser→rarer requirement), so they cannot produce TIR; for example, there is no total internal reflection for rays going from air into water.
