The cyclic ring structure of ozone is known not to exist.This gives proof that the energy of the acyclic structure is much lesser than the ring compound.This is the characteristic nature of anti-aromatic compounds.

since its non cyclic it should be non aromatic

I have updated the answer to non aromatic.

In future, if you spot any errors with a problem, you can “report” it by selecting "report problem" in the menu. This will notify the problem creator who can fix the issues.

can't we use here the formulae of 4n+2 - pi electrons

Antiaromatic molecules have $4n$ number of $\pi$ electrons, where $n$ is the number of rings in the molecule. Aromatic molecules have $4n+2$ number of $\pi$ electrons. A prerequisite for a molecule to be either aromatic or antiaromatic is that it must have have at least one ring. Ozone has no rings; therefore, the correct answer is $non \space aromatic$ .
