B.Beer
C.Wine
D.Yogurt

Answer 1

I believe that the answer is A

Answer 2

The right answer is D. Yogurt

Bread, beer, and wine are also prepared by fermentation, but the micro-organisms here are the yeast, not bacteria.

Yogurt is a milk fermented by the development of lactic acid bacteria Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus which must be sown simultaneously and be alive in the finished product.
