The technique known as level schedules

A) requires that schedules be met without variation.
B) processes many small batches rather than one large one.
C) is known as "jelly bean" scheduling.
D) is based on meeting one day's demand with that day's production.
E) All of the above are true regarding level scheduling.

Level scheduling is a technique that involves all the mentioned aspects: meeting schedules without variation, processing many small batches instead of one large one (to level out the workload), being referred to as "jelly bean" scheduling (due to the even spread of different tasks or products like a mix of jelly beans), and aiming to meet each day's demand with that day's production to avoid overproduction and underproduction.
