Darwin proposed the theory of

Options

A. Inheritance of acquired characters
B. Recapitulation
C. Continuity of gerrnplasm
D. None of the above

Explanation

**Step-by-Step Text Solution:**

1. **Identify the Question**: The question asks what theory was proposed by Charles Darwin.

2. **Evaluate the Options**:
- **Option 1: Inheritance of Acquired Characters**: This theory was proposed by Jean-Baptiste Lamarck, not Darwin. Lamarck suggested that traits acquired during an organism's lifetime could be passed on to its offspring.
- **Option 2: Recapitulation Theory**: This theory was proposed by Ernst Haeckel. It states that the development of an individual organism (ontogeny) follows the same progression as the evolutionary history of that organism's species (phylogeny).
- **Option 3: Continuity of Germplasm**: This theory was proposed by August Weismann, who argued against Lamarck's ideas by suggesting that only hereditary information in germ cells is passed to the next generation, not acquired traits.
- **Option 4: None of the Above**: Since none of the previous options are correct, this option must be considered.

3. **Conclusion**: Since all the options provided do not correspond to a theory proposed by Darwin, the correct answer is "None of the Above." Darwin is known for proposing the theory of natural selection, which is not listed among the options.

**Final Answer**: None of the Above.
