D. If both Assertion & Reason are false.

Answer

### Step-by-Step Text Solution:

1. **Understanding the Assertion**: The assertion states that Charles Robert Darwin strongly challenged the ideas of the special creation theory. This theory posits that life on Earth was created by a supernatural power. Darwin's work, particularly his theory of natural selection, indeed opposes this idea by suggesting that species evolve over time through natural processes.

2. **Evaluating the Reason**: The reason provided states that Darwin was influenced by Lamarck's idea of use and disuse. Lamarck proposed that organisms could change during their lifetime based on their use of certain traits, and these changes could be passed on to their offspring. However, while Darwin acknowledged the existence of variations among species, he did not base his theory of natural selection on Lamarck's ideas.

3. **Determining Truth Values**:
- **Assertion**: True. Darwin did challenge the special creation theory.
- **Reason**: False. Darwin was not primarily influenced by Lamarck's ideas; instead, he was more influenced by Malthus's population theory.

4. **Conclusion**: Since the assertion is true and the reason is false, we conclude that the correct answer is that the assertion is true, but the reason is false.

### Final Answer:
- **Assertion**: True
- **Reason**: False
