(D) For an equilateral prism,the angle of the prism $A = 60^o$.Given that the angle of incidence $i = 45^o$ and the angle of emergence $e = 45^o$.The relation between the angle of incidence,angle of emergence,angle of the prism,and angle of deviation $\delta$ is given by:$i + e = A + \delta$Substituting the given values:$45^o + 45^o = 60^o + \delta$$90^o = 60^o + \delta$$\delta = 90^o - 60^o = 30^o$.Therefore,the angle of deviation is $30^o$.
