High C/N ratio produces

Options

A. Softer tissues
B. More mechanical tissues
C. More growth hormones
D. Growth inhibitors.

Answer

### Step-by-Step Solution:

1. **Understanding C/N Ratio**: The carbon to nitrogen (C/N) ratio is a measure of the relative amounts of carbon and nitrogen in plant tissues. A high C/N ratio indicates a higher amount of carbon compared to nitrogen.

2. **Effects of High C/N Ratio**: When plants have a high C/N ratio, they tend to produce more mechanical tissues. This is because the excess carbon is often used to build structural components like lignin, which contributes to the rigidity and strength of the plant.

3. **Comparison with Other Tissues**: In contrast, softer tissues, which are typically more metabolically active and require more nitrogen, are associated with a lower C/N ratio. Therefore, a high C/N ratio is not conducive to the production of softer tissues.

4. **Growth Hormones and Inhibitors**: The presence of a high C/N ratio does not directly correlate with the production of growth hormones or growth inhibitors. These hormones are influenced by various factors including environmental conditions and plant developmental stages.

5. **Conclusion**: Based on the understanding of the effects of a high C/N ratio, the correct answer to the question is that it produces more mechanical tissues.

### Final Answer:
High C/N ratio produces more mechanical tissues.
