A certain prism is found to produce a minimum deviation of \( 38^{\circ} \). It produces a deviation of \( 44^{\circ} \) when the angle of incidence is either \( 42^{\circ} \) or \( 62^{\circ} \). What is the angle of incidence when it is undergoing minimum
P deviation?
(A) \( 45^{\circ} \)
(B) \( 49^{\circ} \)
(C) \( 40^{\circ} \)
(D) \( 55^{\circ} \)
