Solution
Explanation:
According to the law of reflection, the angle of incidence is strictly equal to the angle of reflection ($$i = r$$). Therefore, the graph between $$i$$ and $$r$$ is a straight line passing through the origin with a slope of 1 (making an angle of 45° with the axes), shown in (d).
