B. Pericycle
C. Pith
D. Cortex

Answer

To answer the question regarding the central most portion of the stem of dicotyledonous plants, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of the Stem**:
- The stem of dicotyledonous plants consists of various parts including the pith, vascular bundles, cortex, and pericycle.

2. **Locate the Central Most Portion**:
- Among these components, the pith is located at the center of the stem.

3. **Understand the Structure**:
- The pith is made up of soft and spongy parenchyma cells. These cells are responsible for storing and transporting nutrients within the plant.

4. **Differentiate Between Other Parts**:
