Detailed Solution

The given statement is true.
Concept- Fermentation is the process of breaking down a substance into simpler substances by the action of bacterias or yeast. This process is useful in making beer, wine, bread, kimchi, yogurt and other foods.
The milk is transformed into curd through the fermentation process. Milk consists of proteins known as casein.
Curd is created as a result of a chemical reaction between lactic acid bacteria and casein.
During fermentation, energy is produced in the form of ATP.
A byproduct of ATP production is lactic acid.
Lactic acid acts on globular proteins present in milk and denatures them. This denaturation destroys the tertiary and quaternary structures of the proteins, and the globular proteins are converted into fibrous proteins, giving the milk a thick texture due to protein coagulation.
Thus, the given statement is true.
Hence, the correct answer is option 1.
