One of the following theories was proposed by Weismann :

Options

A. Law of inheritance
B. Theory of inheritance of acquired characters
C. Theory of continuity of germplasm
D. Theory of natural selection

Explanation

**Step-by-Step Solution:**

1. **Identify the Theories:** The question asks to identify which theory was proposed by Weismann from the given options. The theories mentioned are:
- Law of Inheritance
- Theory of Inheritance of Acquired Characters
- Theory of Continuity of Germplasm
- Theory of Natural Selection

2. **Recall Weismann's Contribution:** Weismann is known for his work on the germplasm theory. He proposed the "Theory of Continuity of Germplasm" in 1896. This theory states that germ cells (sperm and egg) carry hereditary information and are responsible for passing traits from parents to offspring, while somatic (body) cells do not contribute to heredity.

3. **Analyze Other Theories:**
- **Law of Inheritance:** This was proposed by Gregor Mendel, who studied inheritance patterns in pea plants.
- **Theory of Inheritance of Acquired Characters:** This theory was proposed by Jean-Baptiste Lamarck, suggesting that traits acquired during an organism's lifetime can be passed to offspring.
- **Theory of Natural Selection:** This theory was proposed by Charles Darwin, explaining how organisms that adapt better to their environment are more likely to survive and reproduce.

4. **Select the Correct Option:** Based on the information:
- The correct answer is the "Theory of Continuity of Germplasm," which is the third option.

**Final Answer:** The theory proposed by Weismann is the "Theory of Continuity of Germplasm."
