The FCFS (First-Come, First-Serve) algorithm can be particularly troublesome for time sharing systems.

Here's why:

1. FCFS is a scheduling algorithm used by the operating system to manage the execution of processes. The process that requests the CPU first is the one that gets the CPU first.

2. In a time-sharing system, multiple users are sharing the system resources simultaneously. Each user gets a small unit of CPU time called a time slice. The system switches rapidly from one user to another, giving the illusion that each user has their own dedicated system.

3. The problem with using FCFS in a time-sharing system is that it can lead to poor performance and inefficiency. If a process that takes a long time to complete arrives first, it will hold the CPU for a long time, causing other processes to wait. This is known as the convoy effect.

4. This can be particularly problematic in a time-sharing system where the goal is to give each user a fair share of the CPU time. A long process can monopolize the CPU, leading to delays for other users.

5. Therefore, other scheduling algorithms like Round Robin or Priority Scheduling, which allocate CPU time more fairly and efficiently, are typically used in time-sharing systems instead of FCFS.

So, the answer is c) time sharing systems.
