Best answer
Right option is (d) 134°

To elaborate: Ideally, according to its structure, the bond angle between the two oxygen atoms in nitrogen dioxide should be 120°. But, the one lone electron on the nitrogen atom exerts a less repulsion than normal on the two oxygen atoms. So, they spread out more, to form a bond angle of 134°.
