Answer Key : (a) -

(a)

Since prism  is placed in position of minimum deviation, therefore refracted rays becomes parallel to the base of the prism, again by adding two prism  and  of same material as shown in figure, the deviation produced by  and  equal and opposite in sense, therefore final deviation is same as due to prism .
