The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that insect resistance in host crop plants is solely due to physiological characteristics. This implies that only the internal processes of the plant contribute to its ability to resist pests. 2. **Analyzing the Reason**: The reason claims that morphological (structural features) and biochemical (chemical processes) characteristics do not play any role in pest resistance. This suggests that external features and chemical defenses are irrelevant to how plants resist insects. 3. **Evaluating the Assertion**: In reality, insect resistance in plants is influenced by a combination of physiological, morphological, and biochemical traits. For example, the structure of leaves (morphological) can deter pests, while certain chemicals produced by the plant (biochemical) can repel or harm insects. 4. **Evaluating the Reason**: The reason is also incorrect because morphological traits (like thorns or tough leaves) and biochemical traits (like the production of toxins or repellents) are indeed significant in providing pest resistance. 5. **Conclusion**: Since both the assertion and the reason are false, the correct answer is that both the assertion and the reason do not hold true. ### Final Answer: Both assertion and reason are false.
