A given ray of light suffers minimum deviation in an equilateral prism P. Additional prisms Q and R of identical shape and material are now added to P, as shown in the figure. The ray will suffer:

Hint:

The light ray only band when it goes from one medium to another with a different refractive index.

Step 1: Showing the ray diagram,

The ray diagram can be shown as,

Step 2: Conclusion,

$\bullet$As the refractive index of all prisms is the same therefore this can be considered as a whole single body.

$\bullet$Therefore the light ray will not band as there is no change in the refractive index. so deviation is not affected.

$\textbf{Hence, the option A is the correct answer.}$
