D Correct answer
Explanation

Reason - The first level of classification among plants depends on well-differentiated distinct components of plants. For e.g. stems, roots, leaves. The next level of classification is based on the presence of special tissues for transfer of water and other substances in differentiated plant body, i.e. the presence or absence of vascular bundles. The final level of classification is based on the enclosure of seeds within fruits, i.e. the presence or absence of seed covering.  Therefore, (4) is not the criterion as cell wall is present in all plants and is made of cellulose, which makes cell wall rigid.
