The CORRECT statement regarding the substitution of coordinated ligands in $\mathrm{Ni(CO)_4}$ and $\mathrm{Co(NO)(CO)_3}$ is: (Given: Co–N–O bond is nearly linear; atomic numbers of Co and Ni are 27 and 28, respectively)
(a)$\mathrm{Ni(CO)_4}$ and $\mathrm{Co(NO)(CO)_3}$ follow associative and dissociative pathways, respectively.
(b)Both $\mathrm{Ni(CO)_4}$ and $\mathrm{Co(NO)(CO)_3}$ follow associative pathway.
(c)Both $\mathrm{Ni(CO)_4}$ and $\mathrm{Co(NO)(CO)_3}$ follow dissociative pathway.
(d)$\mathrm{Ni(CO)_4}$ and $\mathrm{Co(NO)(CO)_3}$ follow dissociative and associative pathways, respectively.
