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.
In light of the above statements, choose the most appropriate answer from the options given below: 
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.
