Hint: In plants, we can see Epidermis which is a sort of protoderm-derived layer of cells covering the parts of stems, roots, leaves, flowers, fruits and seeds. The waxy-nature covering cuticle of epidermis provides the organs a type of protective layers. Among several salient functions of Epidermis, the most important ones are to protect against water loss, to regulate gas exchange, to secret metabolic compounds and mainly for roots, to absorb water and mineral nutrients.

Complete Answer:
- ZeaMaize is the flowering plant from the grass family. The epidermis of the plants of this genre is basically composed of two types of cells. They are the long calls and the short cells organised in a single layer.
- The epidermis of grass and basically like that of the Zea Maize. They are also single layered with two different types of cells.
- Nerium or commonly known as Nerium Oleanderis cultivated in tropical and subtropical areas as decorations and is a beautiful picturesque site. The roots and flowers of Nerium plants basically have multiseriate epidermis. Hence, we can say that the epidermis is multi-layered only in Nerium.

Hence the correct answer is option A.

Note: Epidermis as we know is mostly single layered. However, those plants in which the epidermis is multi-layered are mostly xerophytes as they need to restrict the release of water to the maximum. Added to that, some plant parts also have double layer epidermis such as that in the roots.
