Given below are two statements:
Statement-I : Ozonolysis of alkenes involves the addition of ozone molecule to alkene to form ozonide and then cleavage of the ozonide by $\mathrm{Zn}-{\mathrm{H}}_2\mathrm{O}$  to smaller molecules.
Statement-II : Ozonolysis reaction is highly useful in detecting the position of double bond in alkenes or in other unsaturated compounds.
In the light of the above statements choose the most appropriate answer from the options given below:
 

The given statements are both true and related to the ozonolysis of alkenes. Statement-I explains the mechanism of ozonolysis which involves the addition of ozone to the alkene followed by the cleavage of ozonide with reducing agent Zn-H₂O to produce smaller molecules. Statement-II highlights the importance of ozonolysis reaction in identifying the position of double bond in alkenes or other unsaturated compounds.

Therefore, the correct option would be:

Both statements are true, and Statement-II is the explanation of Statement-I.
