The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion:** - The assertion states that Complex II and Complex III of the Electron Transport System (ETS) are NADH dehydrogenase and cytochrome oxidase complex, respectively. - In reality, Complex II is known as succinate dehydrogenase, and Complex III is referred to as the cytochrome bc1 complex. Therefore, the assertion is incorrect. 2. **Understanding the Reason:** - The reason states that cytochrome c acts as a mobile carrier for the transfer of electrons between Complex II and Complex III. - However, cytochrome c actually transfers electrons between Complex III and Complex IV, not between Complex II and III. Therefore, this statement is also incorrect. 3. **Conclusion:** - Since both the assertion and the reason are false, we conclude that the correct answer is that both the assertion and the reason are false. **Final Answer:** Both the assertion and the reason are false. ---
