The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the structural and functional unit of inheritance. This means we need to identify what carries genetic information in living organisms. 2. **Analyzing the Options**: - **Chromosome**: Chromosomes are found in the nucleus of a cell and are made up of DNA. They carry genetic information but are not the basic unit of inheritance. - **Gene**: Genes are segments of DNA located on chromosomes. They are indeed the basic units of heredity and are responsible for the inheritance of traits. - **Protoplast**: The protoplast refers to the living part of a cell, excluding the cell wall. It is not directly involved in inheritance. - **None of these**: This option suggests that none of the previous options are correct. 3. **Identifying the Correct Answer**: - Among the options analyzed, the gene is the correct answer. It is the structural and functional unit of inheritance as it carries the information necessary for the development and functioning of an organism. 4. **Conclusion**: The structural and functional unit of inheritance is the **gene**. ---
