System I: relative speed of two particles on the circle separated by 90° is √2, matching S. System II: projectile velocity difference at t=π/3 gives √(25π²+1), matching T. System III: differentiating xₐ and xᵦ at t=π/3 gives relative speed (√3+1)/2, matching P. System IV: one particle has horizontal speed 1 and the other vertical speed 3, so relative speed=√10, matching R. Thus I→S, II→T, III→P, IV→R: option C.
