The rate-determining step in the catalytic synthesis of acetic acid by Monsanto process is
(a)oxidative addition of $\mathrm{CH}_{3} \mathrm{I}$ to $\left[\mathrm{RhI}_{2}(\mathrm{CO})_{2}\right]^{-}$
(b)migration of $\mathrm{CH}_{3}$ group to CO of $\left[\mathrm{RhI}_{3}(\mathrm{CO})_{2}\left(\mathrm{CH}_{3}\right)\right]^{-}$
(c)loss of $\mathrm{CH}_{3} \mathrm{COI}$ from $\left[\mathrm{RhI}_{3}(\mathrm{CO})_{2}\left(\mathrm{COCH}_{3}\right)\right]^{-}$
(d)coordination of CO to $\left[\mathrm{RhI}_{3} \mathrm{CO}\left(\mathrm{COCH}_{3}\right)\right]^{-}$
