The secondary meristem originates from-
(a) Promeristem
(b) Primary meristem
(c) Primary permanent tissue
(d) Secretory tissue

Options

A. Promeristem
B. Primary meristem
C. Primary permanent tissue
D. Secretory tissue

Answer

To solve the question "The secondary meristem originates from-", we need to analyze the options provided and understand the nature of meristems in plants.

### Step-by-Step Solution:

1. **Understanding Meristems**:
- Meristems are regions in plants where cells are actively dividing. They are classified into three main types: promeristem, primary meristem, and secondary meristem.

2. **Identifying Promeristem**:
- Promeristem refers to the initial meristematic tissue that is present in the plant. It gives rise to primary meristems but does not directly produce secondary meristems.

3. **Identifying Primary Meristem**:
- Primary meristem develops from promeristem and is responsible for the primary growth of the plant. However, it does not give rise to secondary meristems.

4. **Identifying Primary Permanent Tissue**:
- Primary permanent tissues are differentiated tissues that arise from primary meristems. Secondary meristems originate from these permanent tissues.

5. **Identifying Secretory Tissue**:
- Secretory tissues are specialized tissues in plants that are involved in the secretion of substances. They do not contribute to the formation of secondary meristems.

6. **Conclusion**:
- Based on the analysis, secondary meristems originate from primary permanent tissue. Therefore, the correct answer is (c) Primary permanent tissue.

### Final Answer:
(c) Primary permanent tissue
