(A) For every angle of deviation, there are two angles of incidence :- true

(B) When angle of deviation is minimum, light ray travels parallel to the base :- true

(C) There are two angles of incidence for maximum deviation :- false
        maximum deviation occurs when angle of incidence is grazing incidence, i.e., angle of incidence = 90°

(D) Angle of minimum deviation will increase if refractive index of medium is increased
     by keeping the refractive index of outside medium as constant :- true
