Explanation:
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports fluids between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue.
but i searched about option d this is the answer i got
Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants. Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant
<u><em>In vascular plants, stems are the organs that hold plants upright so they can get the sunlight and air they need. Stems also bear leaves, flowers, cones, and secondary stem</em></u>

The correct answer is A. Cerebrum
Explanation:
The motor cortex is an area of the cerebral cortex (outer layer of the cerebrum in the brain), this area is the one responsible for movements especially voluntary ones and including the movement of different parts of the body such as the limbs, the jaw, the tongue, the eyeballs, the neck, etc. Additionally, due to the complexity of the motor cortex, this is divided into three areas located in the same zone that include the primary motor cortex, the supplementary motor area, and the premotor cortex. According to this, it can be concluded the motor cortex is part of the cerebrum as it is located in the cerebral cortex which is part of it (cerebrum).
