The reaction of $\mathrm{PCl}^{3}$ with PhLi in $1: 3$ molar ratio yields X as one of the products, which on further treatment with $\mathrm{CH}_{3}$ I gives Y. The reaction of Y with n-BuLi gives product Z. The product X, Y and Z respectively, are
(a)$\left[\mathrm{PPh}_{4}\right] \mathrm{Cl},\left[\mathrm{Ph}_{2} \mathrm{P}=\mathrm{CH}_{2}\right]$ and $\mathrm{Ph}_{2} \mathrm{P}(\mathrm{n}-\mathrm{Bu})$
(b)$\mathrm{PPh}_{3},\left[\mathrm{Ph}_{3} \mathrm{PI}\right]\left(\mathrm{CH}_{3}\right)$ and $\mathrm{Ph}_{2} \mathrm{P}(\mathrm{n}-\mathrm{Bu})_{3}$
(c)$\mathrm{PPh}_{3},\left[\mathrm{Ph}_{3} \mathrm{P}\left(\mathrm{CH}_{3}\right)\right] \mathrm{I}$ and $\mathrm{Ph}_{3} \mathrm{P}=\mathrm{CH}_{3}$
(d)$\left[\mathrm{PPh}_{4}\right] \mathrm{Cl},\left[\mathrm{Ph}_{3} \mathrm{P}=\mathrm{CH}_{2}\right]$ and $\left[\mathrm{Ph}_{3} \mathrm{P}(\mathrm{n}-\mathrm{Bu})\right] \mathrm{Li}$
