If vallecular canals and carinal canals are present in transverse sections of a young stem, then the plant belongs to the order Equisetales, which includes the horsetails or scouring rushes.

Horsetails are unique vascular plants characterised by jointed stems and reduced leaves. The presence of vallecular canals and carinal canals is a distinctive feature of horsetails. Vallecular canals are large air spaces located on the adaxial (inner) side of the stem, while carinal canals are smaller air spaces located on the abaxial (outer) side of the stem. These canals serve to provide structural support and assist in gas exchange within the stem.

Hence, the correct answer is option 4.
