The living mechanical tissue of a dicot plant is :

Options

A. chlorenchyma
B. sclerenchyma
C. parenchyma
D. collenchyma

Explanation

To solve the question regarding the living mechanical tissue of a dicot plant, we will analyze the options provided and determine which one is correct.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the living mechanical tissue in a dicot plant. Mechanical tissues provide structural support to the plant.

2. **Analyze the Options**:
- **Chlorenchyma**: This tissue contains chloroplasts and is involved in photosynthesis. It is not primarily a mechanical tissue. Therefore, this option is incorrect.
- **Sclerenchyma**: This tissue is known for providing support but is made up of dead cells. Since the question specifies "living" mechanical tissue, this option is also incorrect.
- **Parenchyma**: This is the most common type of plant tissue, primarily involved in storage and photosynthesis, but it does not provide significant mechanical support. Thus, this option is incorrect.
- **Cholenchyma**: This tissue is characterized as a living mechanical tissue that provides support, particularly in the aerial parts of dicot plants. It consists of living cells and is found in strands, making it the correct option.

3. **Conclusion**: Based on the analysis of the options, the living mechanical tissue of a dicot plant is **Cholenchyma**.

### Final Answer:
**Cholenchyma** is the living mechanical tissue of a dicot plant.
