Hugodevries' theory of mutation is :-

Options

A. does not opposed natural selection theory
B. opposed natural selection theory
C. contradicted Lamarck's theory
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Hugo de Vries' Theory of Mutation:**
- Hugo de Vries proposed the mutation theory, which states that mutations are sudden, heritable changes in an organism's traits. This theory emphasizes that these mutations can lead to new traits that may be advantageous for survival.

2. **Relation to Natural Selection:**
- De Vries' theory does not oppose the theory of natural selection. Instead, it complements it. He suggested that while mutations introduce new traits, natural selection is the mechanism that determines which of these traits will be preserved in a population based on their fitness in the environment.

3. **Evaluating the Options:**
- Option 1: "Does not oppose natural selection theory" - This is correct because de Vries' mutation theory supports the idea that mutations can be selected by nature.
- Option 2: "Opposes natural selection theory" - This is incorrect as de Vries' theory does not contradict natural selection.
- Option 3: "Contradictory to Lamarck's theory" - This is also incorrect. While de Vries' theory differs from Lamarck's ideas, it does not directly contradict them.
- Option 4: "None of these" - This is incorrect since option 1 is a valid statement.

4. **Conclusion:**
- The correct answer is that Hugo de Vries' theory of mutation does not oppose the natural selection theory.

**Final Answer:**
- The correct option is: **Does not oppose natural selection theory.**
