Yeast has different types of enzyme that convert different sugar into different form based on the environment. For example maltase enzyme is necessary to convert maltose sugar into simple sugar in aerobic condition under specific pH and temperature range. While on the other hand glucose can be converted into alcohol in anaerobic conditions.
Thus, the factors which could affect the respiration pathway adopted by yeast depends on
a) Environment condition including presence of air, temperature and pH
b) Type of food available and enzymes
Hence, both option A and B can explain the experiment results.
Thus, option D is correct
None of the above because all of them can affect homeostasis
