After tracing the path of a ray of light through a glass prism, a student marked the angle of indicence `(angle i)`, angle of emergence `(angle e)` and the angle of deviation `(angleD)` as shown in the diagram.
The correctly marked angles are :
A. `anglei and angle r `
B. `anglei and angle e`
C. `anglei, angle e and angle delta`
D. `anglei, angle r and angle e `
