The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks when August Weismann formulated his "theory of continuity of germplasm". 2. **Identifying the Scientist**: The theory was proposed by August Weismann, a prominent biologist known for his work in genetics and evolution. 3. **Finding the Year**: Weismann formulated his theory in the year 1892. This is a crucial detail as it directly answers the question. 4. **Understanding the Theory**: The theory of continuity of germplasm states that there are two types of biological substances: somatoplasm and germplasm. - **Somatoplasm**: This is present in somatic cells and is responsible for the physical body of the organism. It dies with the organism. - **Germplasm**: This is found in germ cells (or gonads) and is responsible for the transfer of genetic traits to the next generation. Changes in germplasm can be inherited, while changes in somatoplasm cannot. 5. **Conclusion**: Based on the information gathered, the correct answer to the question is that Weismann formulated his theory of continuity of germplasm in the year 1892. **Final Answer**: 1892 ---

Theory of continuity of germplasm was propounded by

Assertion : Human ancestors never used their tails and so the tails expressing gene has disappeared in them. Reason : Lamarck's theory of evolution is popularly called theory of continuity of germ plasm.

Einstein in 1905 proppunded the special theory of relativity and in 1915 proposed the general theory of relativity. The special theory deals with inertial frames of reference.
