• A. Orchidaceae
• B. Iridaceae
• C. Euphorbiaceae
• D. Liliaceae
• E. All of the above

Answer 1

The correct option is C Euphorbiaceae

The study of the vascular bundles in some species of Euphorbiaceae shows the presence of bi-collateral bundles arranged in a ring form. In Euphorbiaceae, the primary vascular tissue consists of vascular bundles, usually in one or two rings around the pith. Vascular bundles are uniform in size. Each vascular bundle is conjoint, collateral or bicollateral and open. Phloem peranchyma are present. Bundle sheath is absent. No water containing cavity is present.
Thus, the correct answer is option C.
