Given the following information, which of the following elementary reactions has the highest frequency (occurrence) with the lowest success of molecular collisions?

Rate law k(s$^{-1}$)
1 rate = k[A]$^1$[B]$^3$[C]$^0$ $ 3.16 \times 10^{-4} \quad$
2 rate = k[A]$^0$[B]$^2$[C]$^1$ $ 6.42 \times 10^{-5}$
3 rate = k[A]$^1$[B]$^1$[C]$^1$ $ 1.26 \times 10^{-3}$
