Which of the following is a difference between line$-$flow production processes and batch production processes?

Group of answer choices

Line$-$flow production processes are inflexible, whereas batch production processes are flexible.

Batch production is used to make a single type of product, whereas line$-$flow production is used to make large quantities of different products.

Line$-$flow production processes are the least standardized manufacturing operations, whereas batch production processes are the most standardized manufacturing operations.

Batch production produces products continuously, whereas line$-$flow production produces products at a discrete rate.
