(D) The enol content depends on the stability of the resulting enol form. In compound $(II)$,the enol form is stabilized by conjugation with the double bond,making it the most stable. In compound $(I)$,the enol form is less stable than $(II)$ but more stable than $(III)$ because $(III)$ involves the formation of an anti-aromatic or highly strained system upon enolization. Thus,the correct order of enol content is $II > I > III$.
