Catenation tendency in group 14 is:...

Catenation tendency in group `14` is:

A

`CgtgtSigtGe=Pb` due to bond energies `C-HgtSi-H gt Ge-H gt Sn-H`

B

`CgtgtSigtGe=Sn gt Pb` due to bond energies `C-CgtSi-C gt Ge-C gt Sn-C`

C

`C=Si=Ge=Sn = Pb` due to bond energies `C-HgtSi-H gt Ge-H gt Sn-H`

D

`CgtgtSigtGe=Sn gt Pb` due to bond energies `C-CgtSi-Si gt Ge-Ge gt Sn-Sn`
