Dear Student,

Total internal reflection occurs when the light travels from denser to rarer when the angle of incidence is geater that critical angle.
in this case tir can take place in water to air and diamond to glass they all are travelling from denser to rarer.

We fixed the options issue.

Keep learning with us.
All the Best.
