(3)

When the light is incident on a glass–air interface while travelling from glass at an angle less than the critical angle, a small part of the light will be reflected and most part will be transmitted.

When the light is incident at an angle greater than the critical angle, it undergoes complete reflection (total internal reflection), resulting in 0% transmission and 100% reflection.

These characteristics are depicted in option (3).
