Solution : The correct option is - Lactobacillus
The fermentation of milk into curd is primarily due to the action of lactic acid bacteria. Specifically, the most common bacteria responsible for this process is Lactobacillus bulgaricus and Streptococcus thermophilus, although other lactic acid bacteria strains may also be involved. These bacteria convert the lactose (milk sugar) present in milk into lactic acid through a fermentation process.
