The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Red Muscles:** - Red muscles are characterized by the presence of myoglobin, a red pigment that helps in oxygen storage and transport. This gives red muscles their distinctive color. 2. **Function of Myoglobin:** - Myoglobin allows red muscles to have a high oxygen-carrying capacity, which is essential for aerobic respiration. This means that red muscles primarily rely on oxygen to generate energy. 3. **Mitochondria in Red Muscles:** - Red muscles contain a large number of mitochondria, which are the cellular organelles responsible for producing energy (ATP) through aerobic respiration. The presence of many mitochondria indicates that these muscles can efficiently use oxygen to generate energy. 4. **Assertion Evaluation:** - The assertion states that red muscles depend on anaerobic processes for energy. This is incorrect because red muscles primarily rely on aerobic processes due to their high myoglobin content and abundant mitochondria. 5. **Reason Evaluation:** - The reason given is that red muscles have a few number of mitochondria. This is also incorrect, as red muscles actually have a large number of mitochondria, which supports aerobic respiration. 6. **Conclusion:** - Since both the assertion and the reason are false, the correct answer is that both the assertion and reason are false. **Final Answer:** - Both assertion and reason are false (Option D). ---
