A
$\angle i$ and $\angle e$
B
$\angle A$ and $\angle D$
C
$\angle i$ ,$\angle e$ and $\angle D$
✓
$\angle r$, $\angle A$ and $\angle D$

✓

Answer

Correct option: D.

$\angle r$, $\angle A$ and $\angle D$

$\angle A$ represents the angle of a prism while $\angle D$ represents the angle of deviation and both are correctly marked.
As angle of refraction $(\angle r )$ is the angle formed by the refracted ray with the normal and is also correctly marked.
But $\angle i$ and $\angle e$ are the angles made by the incident ray with the normal and emergent ray with the normal respectively and thus are incorrectly marked. Hence option D is correct.
