(B) The bond length between carbon atoms depends on the hybridization state of the carbon atoms involved. $sp^3-sp^3$ single bond (as in $C_2H_6$) has a bond length of $154 \ pm$. $sp^2-sp^2$ double bond (as in $C_2H_4$) has a bond length of $134 \ pm$. $sp-sp$ triple bond (as in $C_2H_2$) has a bond length of $120 \ pm$. In $Propyne$ $(CH_3-C \equiv CH)$, there is a $C \equiv C$ triple bond, which has the shortest bond length among the given options.

The bond length between the hybridized carbon atom and another carbon atom is minimum in:
