Concept:In a young dicotyledonous stem, xylem is situated more internally than phloem, and the cambium lies between them.
Explanation:Moving from the centre of the stem towards the outer surface, the correct anatomical order is pith, xylem, cambium, phloem, cortex, and epidermis.
Option C follows this order: pith, xylem, cambium, phloem, collenchyma, parenchyma, and epidermis.
Option A is incorrect because it places phloem before cambium and xylem.
Option B is incorrect because it omits the pith and starts with xylem.
Option D is incorrect because it starts with phloem, which is outer to xylem.
Therefore, only option C correctly shows the tissues from inside to outside.
Answer:Option C
