What does the term 'Inoculum' means when we say that the inoculum is added to the fresh milk in order to convert the milk into curd?

A starter containing millions of LAB.

The correct answer is Option (3) -A starter containing millions of LAB.

The term 'Inoculum' refers to a substance that is introduced into another substance to start a process. In the context of converting milk into curd, the inoculum is a starter culture that contains millions of Lactic Acid Bacteria (LAB). These bacteria are responsible for fermenting the lactose in milk into lactic acid, which causes the milk to thicken and form curd.
