Short term scheduling: It has also known as CPU scheduling, is concerned with selecting a process from the ready queue and allocating the CPU to that process. The goal is to maximize CPU utilization and throughout. 

  • The decision-making process involved in selecting the next process to execute on the CPU from the pool of ready process.

Here, option 1 is correct.
