An alkene on reductive ozonolysis gives 2 molecules of ${\mathrm{CH}}_2\left(\mathrm{CHO}{)}_2\right.$. The compound is

An alkene on reductive ozonolysis gives 2 molecules of ${\mathrm{CH}}_2\left(\mathrm{CHO}{)}_2\right.$. The compound is 1,4-cyclohexadiene.

A total of 14 bonds are present in the 1,4-CYCLOHEXADIENE molecule (s) Two multiple bonds, two double bonds, six non-H bonds, and a six-membered ring are present (s). The term "skeletal formula," which is the accepted nomenclature for organic molecules, is also used to describe the 2D chemical structure image of 1,4-cyclohexadiene.

Hence, option C is correct.
