• D. Flavouring the leaves of tea and tobacco

Answer 1

Answer: (B)

Conversion of milk into curd

Streptococcus lactis is an important bacteria responsible for manufacturing of dairy product, curd. It converts milk into curd by the process of fermentation. It breaks the sugar present in the milk and produces lactic acid. This lactic acid results in the curdling of the milk proteins and produces curd with a tangy taste.

Thus, the correct answer is 'Conversion of milk into curd.'
