The correct Answer is:
D
In `CO_2` molecule carbon atom undergoes sp-hybrisation. `: ddotO=C=ddotO :` The two sp-hybridised orbitals of C-atom overlap with two p-orbitals of O-atom to make 2 `sigma` bonds while other two electrons of C-atom are involved in `p pi - p pi` bonding with oxygen atom. Hence, it is linear in shape with equal C-O bond length and no dipole moment.
