Solution

The correct option is D
In option (d), there is some partial double bond character that arises in $C_{1} - C_{2}$ bond due to resonance.
Also, $C_{1}$ and $C_{2}$ carbons are $s p^{2}$ and $s p$ hybridized respectively. More the s-character, more will be the electronegativity. So $C_{1} - C_{2}$ bond is the shortest.

C1−C2 bond is shortest in:

The correct option is D In option (d), there is some partial double bond character that arises in C1−C2 bond due to resonance. Also, C1 and C2 carbons are sp2 and sp hybridized respectively. More the s-character, more will be the electronegativity. So C1−C2 bond is the shortest.
