- AIt travels back into the water with an angle of reflection equal to $c$.
- BIt travels back into the water with an angle of reflection greater than $c$.
- CIt travels into air with an angle of refraction greater than $\theta$.
- DIt travels into air with an angle of refraction smaller than $\theta$.
