(B) To determine the non-planar species,we analyze the hybridization and geometry of each ion based on $VSEPR$ theory:

	
		
			Species
			Hybridization and Geometry
		
		
			$NO_3^-$
			$sp^2$,Trigonal planar
		
		
			$AsO_3^{3-}$
			$sp^3$,Pyramidal (Non-planar)
		
		
			$CO_3^{2-}$
			$sp^2$,Trigonal planar
		
		
			$ClO_3^-$
			$sp^3$,Pyramidal (Non-planar)
		
		
			$SO_3^{2-}$
			$sp^3$,Pyramidal (Non-planar)
		
		
			$BO_3^{3-}$
			$sp^2$,Trigonal planar
		
	


Species with $sp^3$ hybridization and one lone pair on the central atom,such as $AsO_3^{3-}$,$ClO_3^-$,and $SO_3^{2-}$,exhibit a pyramidal geometry,which is non-planar. Therefore,the correct option is $B$.

Amongst $NO_3^-$,$AsO_3^{3-}$,$CO_3^{2-}$,$ClO_3^-$,$SO_3^{2-}$,and $BO_3^{3-}$,the non-planar species are
