Answer 2

Interrupt handling is not a disadvantage of priority scheduling in OS.

Option: (c)

Explanation:

• ‘Priority scheduling’ can be defined as a non-preemptive algorithm. It is considered to be one of the most commonly used ‘scheduling algorithms’ in batch processing systems.  

• Here, each of the processes are assigned as a priority. The processes with highest priority should be ‘executed first’ and so on.  

• If the processes are assigned with similar priority, then they are executed in ‘First Come First Serve’ basis.  

• Here, the interrupt handling is considered to be the advantage as the interrupts should be given high priority than the ordinary tasks.
