In the light of the above statements choose the correct answer from the options given below:
| Assertion (A): | The maximum concentration of alcohol in beverages that are naturally fermented with yeast is about 13%. |
| Reason (R): | In alcohol fermentation, yeast converts pyruvic acid to ethanol and carbon dioxide. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |

| Statement I: | In fermentation, there is a net gain of 12 molecules of ATP for each molecule of glucose degraded to pyruvic acid whereas only 2 molecules of ATP are generated under aerobic conditions. |
| Statement II: | Fermentation accounts for only a partial breakdown of glucose whereas in aerobic respiration it is completely degraded to CO2 and H2O. |
1. Both Statement I and Statement II are correct.
2. Both Statement I and Statement II are incorrect.
3. Statement I is correct but Statement II is incorrect.
4. Statement I is incorrect but Statement II is correct.
