Light is incident normally on face AB of a prism as shown in figure; A liquid of refractive index \[\mu \] is placed on face AC of the prism, the prism is made of glass of refractive index 3/2. The limits of \[\mu \] for which total internal reflection takes place on face AC is

• A. \[\mu >\frac{3}{4}\]     
• B. \[\mu <\frac{3}{4}\]
• C. \[\mu >\sqrt{3}\]           
• D. \[\mu <\frac{\sqrt{3}}{2}\]
