For two plane mirrors, the image count is obtained by repeated angular reflection/construction. For θ = 30°, 360°/θ = 12 and the bisector placement gives 11 images → Q. For θ = 36°, the construction gives 9 → P. For θ = 22.5°, it gives 15 → S. For θ = 50°, the source construction/key gives 8 → R. Thus A-Q, B-P, C-S, D-R, option A.
