AEvaporation
BFermentation
CCondensation

Answer & Solution
Correct answer: B. Fermentation
1. Sour taste comes from acids, so an acid must have been made in the milk.
2. Fermentation is the reaction that makes those acids in milk and juice.
3. The same process is used on purpose to make yoghurt and cheese.
4. Evaporation and condensation are changes of state and make no new substance.
