Final answer:
Scheduling is done to decrease the turnaround time.
Step-by-step explanation:
Scheduling in computer science is done with the goal of decreasing the turnaround time. Turnaround time refers to the time it takes for a process to complete from the moment it starts until it finishes. By carefully scheduling tasks and assigning resources efficiently, the goal is to minimize the turnaround time and increase the overall efficiency of the system.
For example, in operating systems, task scheduling algorithms are used to determine the order in which processes are executed. These algorithms aim to reduce the turnaround time and ensure that all tasks are completed in a timely manner.
Therefore, the correct answer to the question is: b) decrease the turnaround time.
