The CORRECT order of the CO stretching vibrational frequency is
(a)$\left[\mathrm{Ti}(\mathrm{CO})_{6}\right]^{2-}>\left[\mathrm{V}(\mathrm{CO})_{6}\right]^{-}>\mathrm{CO}>\left[\mathrm{Cr}(\mathrm{CO})_{6}\right]$
(b)$\left[\mathrm{Cr}(\mathrm{CO})_{6}\right]>\mathrm{CO}>\left[\mathrm{V}(\mathrm{CO})_{6}\right]^{-}>\left[\mathrm{Ti}(\mathrm{CO})_{6}\right]^{2-}$
(c)$\mathrm{CO}>\left[\mathrm{V}(\mathrm{CO})_{6}\right]^{-}>\left[\mathrm{Ti}(\mathrm{CO})_{6}\right]^{2-}>\left[\mathrm{Cr}(\mathrm{CO})_{6}\right]$
(d)$\mathrm{CO}>\left[\mathrm{Cr}(\mathrm{CO})_{6}\right]>\left[\mathrm{V}(\mathrm{CO})_{6}\right]^{-}>\left[\mathrm{Ti}(\mathrm{CO})_{6}\right]^{2-}$
