Solution

The correct option is B
Ozonolysis of alkenes involves the addition of an ozone molecule to an alkene, to form an ozonide. Formed ozonide gets cleaved by ZnH2O to smaller oxidised molecules.
In all the given compound all the 3 double bonds form ozonide and gives different oxidised product.
Compound (b) on ozonolysis gives formaldehyde, propan-2-one (acetone) and 2,4-dioxohexanedial


Compound (a) gives propanaldehyde, formaldehyde and 2,4- dioxo hexanedial.

Compound (c) gives acetone, formaldehyde and 2, 5- dioxohexanedial.

Compound (d) gives acetone and 2 moles of formaldehyde.

Thus, the correct compound is (b).
