I have been asked this question during an interview.

My doubt is from Fermenting Sour Tonic Beverages topic in portion Fermenting Vegetables & Milk, Fermenting Sour Tonic Beverages, Non-Food Applications of Fermentation of Fermentation Technology

Answer 1

Correct option is (b) Sodium

To explain I would say: Sodium is present in a very low amount in kvass and therefore kvass promotes the excretion of the fluid. It contains important minerals like iron, copper, sodium, phosphorus, potassium, zinc, fluorine, and B vitamins.
